Battery Life draining significantly all of a sudden

[missestlewis]

Hey guys! I am pretty new to the forum, but after contacting ATT and getting nowhere with them I decided I had to do something else.
About a week and a half ago, my phone just started draining battery. I have had it off the charger for about 3 hours now, and I am down to 53%. By the time I get done with classes around 2:30 it will be dead. My phone used to last me all day (until 7/8 at night), and that is with it frequently being used.
I had not changed anything on the phone for it to do this, everything is the same.
Since then, I have deleted most of my apps, stopped syncing my emails, kept the screen brightness low... and it is still draining battery like crazy.
Within 5 minutes of removing it from the charger its down to 98%, and that's with just removing it, and not using it.
HELP ME PLEASE!



Thanks
-T

Wipe cache partition

If the phone is not working correctly, you may need to master reset it and also clear the cache partition. These two resets clear different parts of the phone storage. Unlike a master reset, wiping the cache partition does not delete your personal data.

To wipe the cache partition, follow these steps:

Turn off the device.
Press and hold the following three buttons at the same time:

Volume Up key
Home key
Power key

When 'GALAXY Note 3' appears on the screen, let go of the Power key but continue to press and hold the Volume Up key and the Home key.
When the Android System Recovery screen appears, release the Volume Up and Home keys.
Press the Volume Down key to highlight 'wipe cache partition.'
Press the Power key to select and wipe the cache.
With 'reboot system now' highlighted, press the Power key to restart the device.

Thanks. This made my device much faster. I had the battery drain with bad lag.

Hey all,
I tried cache reset with no change to battery performance. It looks like I'm having the same issue, though - anything else short of a master reset I can try?

Attached are pre-reset (the one with candy crush) and post-reset (the one with Google play services) screenshots.

I don't know if it's relevant, but Gmail is constantly crashing in the background as well.

Thanks a lot for taking a look - this has made my phone go from "wow, two days on battery, this is awesome" to "hey guys, check out my HTC thunderbolt, it can watch a whole Futurama before I have to plug it in"

37% is a bit much to let the battery go down to. (It's a problem. We don't want 5 pound batteries, so we use lithium, which is the lightest metal. But lithium batteries last longest if only drained about 50%. If we wanted batteries that we could drain flat, then recharge with no problem, lead-acid batteries would work nicely, but would you like carrying a motorcycle battery in your pocket?)

One year of running the battery down could mean end of life. Charging it at the 90% discharge point all the time can give you as little as 300-350 charges before the battery is useless - and if you do that every day, that's about 1 year. Recharging at the 50% point can give you 1,500 charges. Doing that every day gives you 4-5 years - probably longer than you want to keep the phone.

A spare battery is cheap. Swapping batteries mid-day takes a few seconds.
