Replace Battery On Htc One M8 Phone
HTC is steadily increasing the capacity of its batteries built into its mobile devices. A 2000–2500 mAh battery has become the norm today.
But the characteristics of smartphones “grow” even faster: HTC engineers already supply openly budget models with 4.3-inch screens, which for a couple of years have been a sign of the flagship device. Along with the dimensions of the screen, its brightness, contrast, resolution, and, consequently, power consumption are also growing.
The systematic improvement in hardware characteristics confronts HTC phone owners with a problem: the battery runs out quickly, the device does not hold a charge.
Therefore, the issue of saving the charge of lithium-ion and lithium-polymer batteries will remain relevant until a breakthrough in fuel cell technology.
Consider three approaches to increasing the duration of mobile devices:
- Reduced power consumption by hardware and software.
- HTC Battery Calibration.
- Use of external batteries and high capacity batteries.
HTC quickly discharges and heats up: how to reduce the “appetite” of a smartphone?
Often in HTC phones, not only does the battery run out quickly, but the devices also warm up significantly. Why it happens?
The main software reasons for fast energy consumption: background activity and freezing of programs and services. The main hardware sources of heating and discharging: a processor (computing and graphic cores), a bright screen and communication modules.
How to avoid quick discharge
We list the tricks that will increase the life of a phone or tablet from a single charge.
- Change the screen settings: decrease the screen brightness while playing music with the screen locked. Reduce the time interval to automatically turn off the screen.
- Turn on screen blanking while loading web pages. In Sense 5, this is done in the Settings menu. “Special abilities” “Darken the screen while the page is loading.”
- Live wallpapers spend CPU and graphics chip resources on rendering animations. Do not use dynamic wallpaper. Set a static background image, preferably dark.
- Uninstall and disable all unused programs, especially those running in the background (“Settings” “Applications” All Applications tab). Even if the program or widget is preinstalled in ROM and cannot be deleted, they can be disabled. For example, you can turn off standard mail, news, promotions, a browser, HTC Watch, HTC Reader, Google Talk, Twitter, Flickr, Facebook, Dropbox. it all depends on what programs and services you use everyday and whether you installed analogues of built-in applications.
- Disable background processes in the developer’s settings (read here how to activate them): Limit background processes No background processes.
- Keep your programs up to date. Updates often provide improved power consumption and economical memory usage.
- Check program settings that may decrease battery life. For example, instant messengers (Viber, etc.). Do not allow programs to synchronize data too often. Disable background synchronization where it is not needed. For example, in the “Play Store”: “Menu” “Customization”. turn off the auto-update of applications and the automatic addition of widgets. In the OS menu “Settings” “Accounts and sync” check what data is automatically synchronized with your accounts. Do manual synchronization in non-critical applications. Pay special attention to widgets: many of them constantly synchronize data. Remove widgets that are not in urgent need from the main screen.
- Turn off mobile Internet, Bluetooth, Wi-Fi and GPS if you are not using them. Unload navigation programs from memory when you do not need them.
- When moving between the base stations of a mobile operator, especially when you don’t need a connection, temporarily turn on “Airplane mode” so that the phone does not waste charge on network search and switching.
- Turn down the volume of system sounds. Disable vibration confirmation of actions in the Settings menu “Sound”.
- Check battery consumption statistics. This is done in the “Settings” menu. “Nutrition” “Journal”.
Power Saver and Sleep Modes
Starting in 2013, the new HTC models introduced an energy-saving mode. In its settings, you yourself can cut down the appetites of the screen, vibration motor or wireless modem. In the “Power” section, you can also activate the automatic transition of the mobile device to sleep, which means disabling data transfer.
Power Saving Critical: HTC Sense 6.0 New Feature
Owners of HTC smartphones with a Sense shell (starting with version 6.0) can use the critical (extreme) power saving mode, which helps optimize the use of the remaining battery in case of almost full battery drain.
The charge level, after which this mode automatically turns on, is set in the general settings of the smartphone. You can activate the super energy saving mode in the Settings section. Power or through quick settings in the upper status bar.
In critical power saving mode, the user can access only basic functions: calls, messages, mail, calendar and calculator. All communication modules turn off after the screen goes blank. The vibration is switched off, the processor runs at a cut-off frequency, the screen brightness decreases.
Software power consumption on HTC: how to find and fix leaks
First, consider the important issue related to OTA updates. After each major (for example, changing the OS version) update, it is recommended to reset the phone to factory settings. It is not worth immediately evaluating the battery’s “gluttony” after updating and hardware reset, but after two or three days.
When assessing energy consumption, it is customary to focus on the “Android System” indicator in the battery usage log. But this indicator does not always allow an adequate assessment of the situation. Typically, with active use of the phone, the charge on the “Android System” is a few percent. But if the phone “lies on the shelf” and is used only for calls, the “Android System” will consume several tens of percent.
Another common question: why, starting with HTC Sense 6.0, the HTC BlinkFeed process takes the first place in the statistics of battery consumption? The answer is simple: now Sense’s proprietary shell is called BlinkFeed. You can turn off the news screen altogether, but a program with that name will still be in the lead in using battery applications.
It would be more correct to install special programs that monitor application activity: PowerTutor, Wakelock Detector, Battery Monitor Widget. Having accumulated statistics, you will find which programs and services often wake up the device, consume processor time and memory (usually these are background media services, news updates, social networks, weather, location).
Revealed the “culprit” who sets the battery? Disable it: “Settings” “Applications”, select the program, click “Force Stop”, “Clear Data” and then “Disable”. Disable all unnecessary programs this way.
Do I need to turn off Wi-Fi, Bluetooth, GPS and NFC to save power?
The load on the battery from the processor and screen can only be reduced by cardinal methods: do not play games, do not watchs, do not set the screen brightness to 100%. But in this case, it makes no sense to use a smartphone as a mini-computer. The latest chipsets independently monitor the frequency, load and energy consumption, so it is advisable for the user to focus on those aspects that he is able to really change: in particular, on wireless communication modules.
First of all, we note the obvious: if you never use a specific module, you should completely disable it in the settings. If, however, sometimes, but you still need one or another wireless interface, leave it turned on.
- The most “gluttonous” wireless module is Wi-Fi. Today, almost all smartphone owners use Wi-Fi on an ongoing basis. For example, the BCM4335 chip installed in HTC One has effective algorithms for reducing power consumption when idle, so you can safely leave Wi-Fi on all the time. With a good signal from a wireless router or access point, you may not activate the option “Maximum Wi-Fi performance”. Also make sure that the wireless network is turned off in standby mode (“Settings” Wifi “Additionally” “Keep the connection in sleep mode” “Always On” “Never”). Uncheck the option “Scan is always available” in the same menu.
- Bluetooth 4.0 consumes up to 15 mA at peak load (earlier versions of Bluetooth consumed about 25 mA). In addition, during idle time, Bluetooth 4.0 does not require power at all. So there is no need to disable Bluetooth in modern smartphones.
- NFC power consumption is very small even when reading data from NFC tags. So disconnecting this communication module makes no sense.
- GPS consumes energy only during data exchange with satellites (when an easily recognizable icon appears in the status bar). For the rest of the time, GPS stays in the background without consuming battery power. If you use programs and widgets that require determining your location, you do not need to completely turn off GPS to save power.
HTC Battery Calibration
To extend battery life and increase stability, follow these tips:
- Make sure you use a compatible charger (output: 5 volts / 1 / 1.5 amperes. varies by model).
- Do not use recharging from the computer’s USB port too often. Avoid using “non-native” chargers with excessively high amperage (for example, 2 amperes and more): the charging time will decrease, but battery wear will accelerate.
- Every two to three months, completely discharge the battery and charge the smartphone in the off state for at least four hours.
- Avoid discharging the battery periodically to the minimum value. Feel free to recharge the battery if the remaining capacity reaches 25–50%. lithium-polymer batteries are not affected by the memory effect, so they do not need to be “rocked” and discharged “to zero”. But a long stay in a state of almost full or complete discharge adversely affects the resource of their work.
- Tip from HTC support: after purchase, you need to charge the device for 8 hours. It is also necessary to periodically calibrate the battery (cyclic charging of the device): this will refresh the battery and make it more stable. When the battery runs out to 15%, turn off the phone completely. Put it on charge for 15 minutes, then take a break for 5 minutes (removing the phone from charging), then repeat the “fifteen-minute charge. five-minute break” cycle two more times, and then charge the battery to maximum.
Question: why the smartphone does not charge up to 100%, stopping at 95–99%?
We advise you not to pay attention to these conditional percentages. The green LED lights up when the battery is almost full of its full capacity. The charging process can be stopped. This charging of the batteries complies with the rules for their use.
If you want to see the cherished 100% capacity on the screen, hold the phone on recharge for another half an hour or an hour after the green signal lights up. Please note: two to three minutes after the cessation of charging, the percentage of battery charge will drop from 100 to 95–98 points. This is normal and does not indicate a battery defect.

External batteries and rechargeable batteries for HTC
In the matter of increasing the duration of the smartphone, you can go an alternative way: do not cut power consumption, but increase the battery capacity or have a safety net in the form of an external battery.
Spare or larger battery
The capacity of high-capacity batteries for HTC varies. Usually it is from 2000 to 5000 mAh. A back cover is often supplied with a reinforced battery, replacing the standard back panel if the dimensions of the extended battery are larger than the dimensions of a standard battery cell.
It is not at all necessary to look for a reinforced battery. Many do this: they buy one or two spare batteries of standard capacity, simply replacing a dead battery with a fully charged one.

External battery for HTC
What to do if the battery on your phone is non-removable or you will be forced to do without electricity for a long time? An external charger with its own battery will come to the rescue.
Such a gadget usually has a significant capacity (3000-5000 mAh and above). Just connect a portable external battery to your phone via micro-USB cable and your phone will recharge on the go. Useful on the go or traveling. The external battery itself is charging from the computer.
