Battery Behaving Abnormally!!!

[KUMAR MAYANK VIPAL]

Since Past 3 days my battery has became a pain to use.Its won't last more than 4-6 hours even when the battery is 100%.And then to charge the battery to 100% it takes more than 5 hours.My Usage are moderate ,i have my 3g data always ON,and location ON.Rest a bit of small games ,little whatsapp,and next to null browsing.i would like some advice on what to do,i don't want 2 days of battery life but at least 15-16 hours is required.
I Have attached a few screenshots of my battery stats and they are terrible.

Did it start happening about the time you installed the Live Lockscreen beta? I don't have it so I can't say I've noticed it draining battery, but may be worth uninstalling that and/or any recent apps. Only other thing I suggest is if you have Cortana running in the background and pinned, turn her off and unpin or go with the small tile. That helped on my Icon.

I am also facing battery issues from 2 days. In on wp 8 and not on 8.1 with no new apps. I usually charge under airplane mode for quick charging. It is taking more time than usual and battery drain is also more.

Have you tried restarting the phone? To the OP, looks like WhatsAp is using a lot of power - it's a known battery drainer. Try disabling it for a while and see if that helps.

hm. soft reset i think. i havent encountered such problem yet. 4-5hrs of usage time is worst.

I can see you have background processes allowed. You may want to tap "show all apps" and block the rest unless you really need it. Also, in the case of my 720 and 1020, Battery saver turned on ironically drains battery instead of saving it. I also tried battery doctor app for diagnosis because my phone is heating up and battery drains quickly. The cause turned out to be the airplane mode and battery saver both turned on. My phone is normal now.
