How long does a phone battery last? No mouse required. Use only original chargers
Working hours modern smartphone battery power is usually quite limited. Especially if you often actively use the functions of your smartphone: play games, use the Internet, navigate. A smartphone battery is designed for a certain number of charge-discharge cycles.
Side factors also affect the battery life of a smartphone - temperature regime , smartphone charging mode, usage activity.
1. Disable smartphone functions that you are not currently using.
That is, turn off the navigation module (GPS), Internet connection, Wi-Fi, Bluetooth, if this moment you don't need these features. If you use these functions “in vain”, you will drain the battery and reduce its life.
2. Do not allow the battery to be deeply discharged.
For example, deep discharge batteries instantly damage lithium-ion and lithium polymer batteries. But in smartphones and batteries, a special controller is installed that does not allow deep discharge, so the smartphone turns off when the battery signals a low charge level. Therefore, as soon as the device is discharged, put it on charge. Don’t wait for the battery charge to drop even more, and especially don’t try to “finish off” the battery by trying to turn on your smartphone when it turned off due to low level charge.
3. Follow the charging mode.
Maintain full discharge-charge cycles at least 3-4 times a month. Lithium-ion batteries, which are used in most modern smartphones, have a memory effect. That is, if the battery does not produce its full power for a long time, its power decreases. Also don't allow too much long charging. Although the battery controller interrupts charging when the device is already charged, the battery is idle.
4. Use original charger.
And if this is not possible, do not charge the battery with a charger whose power exceeds the power of the original charger. That is, if the power of the original charger is 500 mA, it is prohibited to charge the smartphone with a charger with a power exceeding 500 mA. Otherwise, this will significantly reduce the battery life, and may even damage the battery.
5. Avoid the heat.
A smartphone battery will wear out much faster in high temperature conditions. It doesn't matter whether you use the device or not. Leaving your smartphone in the sun in summer is an extremely bad idea. High temperatures can damage not only the battery, but also the device itself.
6. Battery storage.
Don't buy a spare battery. The battery life still decreases, even if you don’t use it. Well, if you need to store the smartphone battery for some time, then charge the battery by about 40-50%. If a completely discharged battery is left for long time, then over time it will lose its capacity.
Every third app on iPhone and Android uses location services to update data based on GPS. They are also used to instantly search for available bonuses and advantageous offers in a specific region. This reduces battery life, so either disable or keep an eye on your current apps. When you activate search in top panel a small arrow appears in the menu. This way you can track the activity of the program.
Watch out for the pop-up notification
Let's think about how often the battery is drained due to these invisible messages on the lock screen. It seems to you that it is not enough, but they work in such a way that they constantly require power. With each message from the network, the phone is forced to turn on and also make a sound or vibration. All this drains the battery, especially in the case of batch updates. You can turn off this fuss in Settings or in applications, leaving only the essentials for yourself.
Put black or dark wallpaper
If the display phone AMOLED, which is typical for Android gadgets, know that when using a light tone, each pixel of the screen requires a piece of energy. There is no such thing on the iPhone. Therefore, the darker the pixels, the better. Not only wallpapers, but also applications are best used with dark colors.
How about airplane mode
This is best done if network coverage is unreliable. The fact is that the OS is constantly looking for a network when there are interruptions, which is unlikely to please the battery. Putting the phone in airplane mode stops the search, as well as the ability to receive calls and make calls.
Installation of special software
For Android devices, we recommend downloading Snapdragon BatteryGuru from Qualcomm. The application is interesting because it studies the user's habits and automatically adjusts the phone's functions to prolong the battery charge. The iPhone, unfortunately, does not have a similar equivalent, but you can install power saving apps.
Remove unnecessary software
A necessary and requested step. A bunch of unnecessary programs eat up the charge in background. They are disabled in the Applications menu using the Stop or Force Stop command. Special attention Pay attention to the default programs, there is room for developers' imaginations to run wild.
Reduce screen brightness
An obvious step that is often forgotten. back side: If the smartphone is used mainly during the daytime, this solution will be uncomfortable.
Turn off Wi-Fi
An effective step to save battery life. It is often not used due to the owner’s laziness or if he constantly hangs up on the Internet. When you turn it off, the phone stops searching for the network and, accordingly, the charge is extended. When Wi-Fi is always on, there is a high risk of catching viruses from SMS or accidentally downloading suspicious software.
Do not overheat the device
Surprisingly, but true: if you keep your smartphone in the pocket of thin jeans or tight-fitting pants, it will overheat. Overheating entails not only fast discharge batteries, but shortens the lifespan. Of course, you can’t hold your smartphone in direct sunlight. Even schoolchildren know this.
This advice sounds like a joke, but it is common sense. When using your smartphone intensively additional battery will be a good buy.
If our advice helps someone, we will be glad. Check and leave your comments and reviews.
A smartphone is the gadget without which to modern man quite difficult to get by. But none of its functions will work if the battery runs out. Today smartphones with removable batteries are becoming less and less common, so you need to properly handle the default one installed on your device. This is not difficult to do if you follow a few simple rules.
1. Main rule
To extend battery life, you should not keep Wi-Fi and GPS on all the time and spend a lot of time playing games. You should use your phone as needed, not out of habit.But there are other secrets that will keep your battery working for a long time.
2. Avoid completely discharging the battery
Surely, many have heard about the “memory effect” of a battery. It lies in the fact that if you do not “teach” batteries to fully reveal their potential, discharging them completely and then charging them to 100%, then they “lose” part of their capacity. But modern devices use lithium-ion batteries, and they need to be charged differently.To obtain maximum return from lithium ion battery, you need to make sure that the charge level does not fall below 50%. On the one hand, this means that the battery needs to be charged as often as possible, but on the other hand, few people want their battery to overheat (which is the case with lithium-ion batteries Maybe). Fortunately, new charging device smart enough to help the user cope with this problem - they automatically turn off when the phone is charged.
Most manufacturers have approximately the same indicators for the number of charging cycles: if you charge the battery from scratch, the battery will withstand 400-600 charging cycles, and if with 10-20%, then 1000-1100 cycles.
3. Keep the battery in a cool place
A serious enemy of lithium-ion batteries is heat. The smartphone battery will wear out much faster in conditions high temperatures, regardless of whether the device is in use or not.At average temperature At zero degrees Celsius, a lithium-ion battery will lose 6% of its maximum capacity per year. If the outside temperature is +25 degrees, then this figure will increase to 20%, and if it is +40 degrees, the battery will lose a whopping 35% of power over the course of a year.
Of course, you shouldn’t go to extremes and keep your phone in the refrigerator, but you shouldn’t leave your phone in a car hot in the sun either.
4. Avoid wireless charging
Wireless charging is certainly convenient, but it has a number of disadvantages. Inductive, wireless chargers have one unpleasant feature- they heat up the battery. And, as already mentioned, lithium-ion batteries cannot withstand overheating.5. Keep the battery partially charged
Lithium-ion batteries should be stored 30-50% charged. If a completely discharged battery is left for long-term storage, it will no longer “come to life”.6. Be simpler
Caring for the battery is quite easy. As a rule, the service life of a lithium-ion battery is 3-5 years, and during this time many people manage to change more than one smartphone. You just shouldn’t treat the battery like a barbarian - leave it in the sun or discharge it to zero, and it will serve faithfully for quite a long time.Well, don’t forget about such a device as external battery.

Smartphone battery: how to properly operate and charge
All smartphone owners are well aware of how quickly their battery drains. After all, we all use Wi-Fi to surf the Internet, watch videos, and play games. All this rapidly reduces time battery life devices. As a result, the smartphone battery has to be charged every day. This, in turn, shortens its service life. Moreover, if the smartphone has a built-in battery, this reduces the service life of the gadget itself. Therefore, it is important to know how to properly charge your smartphone battery. We talk about this in this material.
Modern smartphones use lithium-ion and lithium-polymer batteries. Today you can find quite a lot of recommendations on how to charge these batteries. Because of this, confusion arises in the user's mind. Some people say that your smartphone battery should be completely drained before charging. Others refute this, saying that it is impossible to discharge below 40 percent and should be immediately charged. Opinions also differ on the upper limit of the charge. Some say that 80-90 percent is enough, while others say you need to charge your phone battery to capacity. We advise you to read about.
The process and frequency of charging a smartphone
Such conflicting advice arose because previously mobile phones and other gadgets we met. They have a pronounced “memory effect”. Therefore, they must be completely discharged before charging. Lithium batteries do not have a “memory effect” and do not need to be discharged before charging. And even undesirable except for a few cases, which are discussed below.
No need to discharge Li-Ion battery smartphone to zero. It's better to constantly recharge it. The table below presents the results of specialist research regarding the service life of lithium batteries depending on the charging mode.
The table shows the dependence of the number of battery cycles depending on the depth of its discharge during operation. According to this data, it is better not to discharge the phone below 80 percent of its full capacity. Of course, this is not always possible, since it requires permanent access to the charger and electrical network. So, we advise you to charge it before its charge drops below 20 percent.
At the same time, the gadget’s battery does not need to be constantly charged to 100 percent. A lithium battery functions normally at a charge level of 50-80 percent. It is best to maintain the charge within these limits during operation. No need to keep charging lithium battery after it has reached 100% capacity. This will shorten its service life.
Of course, in the majority quality phones famous brands The charging controller cuts off the current supply to the battery when fully charged. But if you bet battery smartphone to charge at night, it is better to use energy saving devices, disabling the charger. We also advise you to read about.
You just need to wait until the smartphone turns itself off due to a dead battery. And then charge the battery to 100 percent. This is done to calibrate the battery. As a result of many small discharges and charges, the calibration function begins to malfunction. And such a complete discharge-charge cycle allows the calibration to return to normal. In order to have an idea about this process, read the article about and.
Tips to Increase Smartphone Battery Life
Charger
It is best to charge the battery with the standard charger that comes with your smartphone. These devices are manufactured either by smartphone manufacturers themselves or under their control.
Therefore, such chargers satisfy all battery charging requirements. Namely, voltage, power, output current, etc. There is also third party manufacturers , producing certified chargers either for specific models
, or universal. But finding them on sale is quite difficult, since the shelves are full of counterfeit memory devices produced without any control from the manufacturer. If you charge your phone battery with such devices, this will not help increase its service life. All of the above is also true for. Now on smartphones and tablets there are games with incredible graphics and gameplay that would have raised eyebrows even on a PC ten years ago. For example, in 2014, ten years after its release personal computers, to tablet Nvidia Shield Tablet (Google Android ) the game appeared Half-Life 2. So mobile games are no longer the lot of casual housewives, and the problem of device durability is becoming very acute.
In this article, I will describe the main problems with durability and obsolescence of smartphones and tablets that mobile gamers may encounter. My smartphone gave me the idea for this material. Samsung Galaxy Note, when Wi-Fi failed on it and critical problems with the battery began.
So, the summer of 2015 has come to an end, four years have passed since I got a smartphone in my hands Samsung Galaxy Note GT-N7000. The model was innovative and became the first popular phablet (smartphone with a larger display, from Phone + Tablet, smartphone + tablet). It is noteworthy that it was at that moment that I stopped filming reviews of gadgets and decided to noticeably moderate my ardor in terms of purchasing them. At that moment, the first devices with four cores came out, which turned out to be not particularly better in performance than dual-core ones - development slowed down mobile technology, it no longer provided +100% performance for the year.
So since then I've only got three new devices, including a laptop and a couple of tablets (Windows and Android). And all this time, the same Galaxy worked as the main smartphone Note first generations. Over the years, several facts have accumulated about the obsolescence of devices and their failure, which are worth knowing before purchasing.
- Average term The service life of a smartphone is from 1 to 3 years, most often 2. 4 is a lot and very bad for the user.
- There are cases when smartphones work longer, but this is more a rarity than the general picture.
- If the battery in a smartphone cannot be replaced, then the service life is limited to ~1000 charging cycles.
- It is better to buy a smartphone half a year after the start of its sales, as there is less chance of buying a defective sample.
- There are many factors that influence longevity and the brand is not important here. Acer lives with me longer than Samsung and alive and well.
- Cases and films are really important, without them scratches and damage are inevitable even with Gorilla Glass.
- All games, even the newest ones, continue to run on the Galaxy Note. Two cores and four years are not a problem.
- The exception is games supported by Nvidia, I play them on an Acer A510 (with Tegra III on board).
Will my Android smartphone be obsolete for gaming in four years?
A smartphone or tablet with two cores is still relevant in games if the device resolution falls under the HD standard or lower. Four Cortex A7 cores, by the way (for example, Nvidia processor Tegra III) is also only enough for HD resolution, but with more pleasant graphics. I have a quad core Acer A510 and games run great - no FPS drops at medium graphics settings. Yes, if you didn’t know, it’s already been three or four years mobile games There are graphics settings that help games adapt to different hardware.
So if you buy a modern flagship, it will not be outdated for gaming general understanding- the games will still work after a couple of years, but some of the effects or graphics settings will have to be set a little lower than on more recent models. Everything is the same as on personal computers.
Will the graphics be better on new models of smartphones and tablets?
Now in Apple iOS and MacOS X added support for the new Metal API - this is a connection between the video card and the games that run on it. The better the connection, the faster the games run and the richer their graphics can be ( more effects and technologies can be shown simultaneously). It will also be changed for Android graphics API- OpenGL will be replaced by the Vulkan API. I can’t say anything about how quickly they will be able to implement it. But today there is OpenGL ES 3.0 - this is definitely a dead standard on arrival, which began to be actively used only this year and will not be used anymore, because Vulkan will appear in Android 6 - faster in work, faster in game development.
This means that if you buy a smartphone now, it's important that it can be upgraded to Android 6 if you want to see groundbreaking graphics in three to four years. And, most likely, support for OpenGL ES 3.0 will also be important for the Vulkan API to work on the device. This is a rare case when there is a possibility that on a huge number of old devices, a significant part of the new games will not work at all. And where the games do work, there may be huge differences in graphics.
So on new models (in in this case) The graphics will really be much better in a couple of years. But now I don’t see much difference in Modern Combat 5 on new smartphones or in it on old ones. Same with Real Racing, Asphalt, Shadowgun and other hits.
How quickly does a smartphone break and is it worth overpaying for the brand?
Smartphones from top brands often receive used O more support service centers, this is the only reason to take them. If they're broken, find them new part simpler and this increases the service life. But otherwise, everything is not so simple - surprisingly, first-tier brands are prone to breakdowns no less often than the worst China. The so-called B brands turned out to be somewhat stronger and more durable, although it is not always possible to send them for repairs.
In most smartphones, the first problems can begin within the first year, less often within two. Absolutely any part can break or malfunction - battery, display, buttons, camera. In my case, two years later, the battery of the Galaxy Note swelled and damaged (by an electrical surge) all the power circuits, problems began with the display, and when the charge was less than 30%, it began to blink. Replacing the battery did not solve the problem; until the very end, the smartphone acted up for the next two years. I didn’t replace it for a number of reasons, one of the main ones was the desire not to pollute the planet extra rubbish(the damn greenies brainwashed me).
Before writing the article, I talked with some friends who are still working in the field of IT journalism. Their service life of one device is usually a year, because then the model is replaced with a more recent one - their profession allows it. But not all previous devices go to AVITO; some go to friends and family. So you can find out about the service life quite easily - the same two years, maximum three. It’s very rare for four years if a person doesn’t mind suffering from an obviously faulty gadget.
So it’s probably NOT worth overpaying for the brand. It is more profitable to take devices with a focus on China (for example, Lenovo K50-T5 - no name at all) or Russian brands (they have better support and guarantees, localized Android, etc.). Buying a cool flagship for 50 - 100,000 will not bring any real benefit in terms of durability. And only Nvidia thinks about games for their hardware. Samsung, for example, pushes affiliate games (read casual crap), which cannot always be removed. Majority budget flagships will also last two to three years, and any expensive flagship will still lose its value during this time.
What are the conclusions?
You can play on a smartphone and tablet even four years after release, if it even survives until that time. The problems of hardware obsolescence here certainly cannot become an obstacle in the event flagship models, what can not be said about the hardware itself - it can fail. And this happens on any brand, unfortunately - Samsung or Apple are no exception. But at the moment we are standing on the threshold new era For Android games- Vulkan API release ahead. So now is the only moment in the coming years when it’s worth waiting Android release 6 and the models on it for the sake of the new standard. And feel free to take him for two or three years of active games.
If you want to see cool graphics today and now and get it in the future, then take the iPhone 6 Plus with the Metal API. Everything is already working there and the first games on this combination can already be tried out. Yes, they are expensive, but they lose noticeably less in price than Android flagships. And the service life may be slightly longer, because when official guarantee Replacement of problematic parts is done quickly and up to the entire gadget. Of course, you can also fly in with Apple for repairs - in the last 2-3 years the number of problem devices they have has increased noticeably.
