[Q] horrible battery life since KitKat update Sprint g2.

DopePedaler · Apr 5, 2014

Any other g2 users having major battery issues? Sprint g2, some apps and bloatware frozen/removed. Rooted as well. Battery dropped 38 percent in 4 hours with little to no use. Location services are off. Shows that android operating system using around 40 percent. Any idea of what is causing this? So far, not loving the update and the issues its having.

Absolutely not... Quite the opposite. I'm on a custom ROM but I used ZV7 ZV8 & ZVA before with no issues. That's one great thing about the G2 is the Snap Dragon processors are great on the battery, a charge lasts a long time and the battery never gets hot even with constant tethering and heavy usage. You should try the Snap Dragon battery guru app in the play store at: play.google.com/store/apps/details?id=com.xiam.snapdragon.app which is great for saving juice. Or takes a couple days to get full effect cause it learns your patterns and stops apps from refreshing during times when you don't use them, cuts of WiFi and or data during times when you aren't using it. Also I'd check your battery usage stats and see what processes are draining it the most. Is most likely an app or 2 draining a lot of your battery, so the battery guru will stop that from happening during times that you don't use those apps.

Its very common after a firmware update for a battery to go outta whack. It may be that you need to recalibrate it. After any firmware update its adviseable to so a factory reset at 100% battery level. Then use your phone normally till the battery dies and phone shuts down. Plug in the phone and let it charge to 100% while off. Turn it on, and use it till the batt dies again. Repeat charging to 100% with phone off.

That may solve your issue. Fully cycle the battery 2x.

Thank you @bigpoppa and @sudosurootdev I will try both suggestions. I've got snapdragon app downloaded now. Haven't did a full cycle charge on it yet though. Normally had great battery life, even on aosp roms. Could be that I am just impatient too though haha.

Battery life is greatly affected by weak signals. It drives up the power to get you signal

My signal has actually been a great deal weaker since the update. I live in an.area where there is only 3g/1x data. Used to get around 1.8 mbps download...now only getting around 600kbps. Pretty much just sucks.

I'm having the same issue. It's wakelock WifiOffDelayIfNotUsed. I've tried everything I can think of, but it's completely keeping my phone from deep sleep.

DopePedaler · Apr 7, 2014

I did one full cycle charge. Took it off the charger at around 10am yesterday. Almost 21 hours later, sitting at 35%. Doing a little better than before. Bluetooth keeps showing on my list of wake locks but it's disabled.

I got the ZVC OTA, then I flashed the zvc .tot after accidently deleting supporting services for voice mail (Skyfire Observer and Sprint Extension provider) after flashing Im at 7hrs 30mins Screen Time surfing web with 15% battery left on first day, before that I got little over 6hrs with 0% battery and all the same apps. Do a factory reset after OTA that might help or flash the ZVC.tot for a complete fresh install like I did.

Just an FYI Swype connect is a known battery killer for some its mentioned on their forums and it sometimes runs even when all connect features are blocked.

Another thing block location services when not needed it will save a nice amount of battery life.

I noticed that this morning. I went into wifi settings and clicked advanced and unchecked "scanning always available". Im using "liquid Smooth 4.4 so I don't know if yours have it.

I think its a problem with 4.4.2, google is fixing that in 4.4.3. Also make sure Sprint Connections Optimizer is really off.

The only issue I've seen is Bluetooth showing up under battery stats as being used at around 50-55% yesterday with a runtime of over a day. I'm thinking its just a reporting bug since I haven't used Bluetooth at all and I don't see a noticeable drop in battery but if it is using it I'd definitely like to curb it.

anyone with a similar issue or possible idea on fixing it? Running stock zvc unrooted

That's weird, never had that happen to me. Did you Factory reset after OTA? Sometimes that helps.

No I haven't. I guess I'll give that a shot. But sucks to have to redownload my apps n such for that.

I get 7.5 hrs and 15% battery left at 50% Brightness, location and autosync drain battery a lot as I mentioned before. Also use task manager to autoblock Sprint apps and uncheck Sprint Connections Optimizer it eats battery, Lastly Swype connect runs even when online features are disabled and eats battery, there are many complaints about that on Swype forum as well.

Im mostly on WiFI and have full signal due to Airave (no LTE) so I guess that helps too. All those things add up, I'm sure you can achieve that screen time as well.

By factory reset, do you guys mean in settings? I need to reset, but I don't have a computer at the moment so I can't reflash tot.
