You love your phone, but do you sometimes wish you could change a few little things to make it run better? When it comes to the hardware, there isn't much you can do. However, software is a different story, and with some simple tweaks, you can get more juice from your HTC One M8.
There have been times when my phone has quickly discharged itself. In all of those cases the problems were related to improper settings and rogue programs. I have achieved battery life improvements using nothing more than the stock programs supplied with Android. So, here are a few simple tips to help you do the same...
Adjust BlinkFeed settings
HTC's version of Android, Sense, includes BlinkFeed, which is a nifty way to keep a finger on the pulse of articles you are interested in – but it can sap your battery and even contribute to data overages. This adjustment can help: With BlinkFeed on your screen, swipe your finger to the right. You'll see three vertical dots for the BlinkFeed menu; tap Settings, select Auto Refresh, then choose "Using Wi-Fi" (rather than "Using mobile data or Wi-Fi"). Using Wi-Fi for syncing is easier on your battery than engaging the phone's cellular radio. Not a BlinkFeed fan? Disable it altogether: Pinch two fingers together on your home screen, tap and hold the BlinkFeed icon, and drag it to the trash on the left corner of the screen.
Monitor how much you're syncing
To continue with that theme, you can give other applications that sync regularly a respite. From your home screen, go to Settings. Under the Personal category, choose Accounts & Sync. You can individually manage each account here, either editing syncing schedules or disabling sync altogether. By default, applications tend to sync frequently. Many can be set to only sync when you open up the app.
Wi-Fi is good, cellular can be expensive
The cellular radio in your phone is more power hungry than the Wi-Fi radio. To preserve juice, stick to Wi-Fi as often as you can. To update apps only when Wi-Fi is available, go to the Settings menu, select About, and then choose Software Updates. Check the box for the "Update over Wi-Fi only" option.
Tweak CPU performance
Adjust your CPU without compromising performance in the Settings menu. Under the Phone heading, select Power. Don't enable the Power Saver option. It will turn on automatically when your battery is low. In the Power Saver submenu, check the box for "CPU power," which will ramp down the processor speed and conserve CPU usage when possible.
Switch off Bluetooth and NFC
While Bluetooth is on, the phone continually scans for devices to pair with. This saps battery power. Only keep Bluetooth on when you're actively using it to say, connect with a wireless headset or speaker. (You can switch Bluetooth on or off in Settings, under the Wireless & Networks section). Another thing you may not know is that NFC is turned on by default, and it's a small but constant drain on your battery. So if you are not actively using NFC to connect with other devices, keep it off to help preserve your battery. (It's located in the "More" section under Wireless & Networks in your phone's main Settings).
