Please help! Battery drains in 3 hours by light use!

So, I was reading up on ART vs DALVIK and decided to switch to Art to test it out. Well, after switching I noticed that my battery went from 80 percent with an estimate of 7 hours and 41 minutes to 80 percent with an estimate of 2 hours. I decided to do a factory reset and am still seeing that it has a low hour count anywhere between 1 to 3 hours. Its been about 30 minutes and the phone is now at 68 percent. At one point it went back to 7 hours, but went back to being 1 hour and 4 minutes.
Any advice would be greateful!

First off stop looking at the estimated time left cause it's never correct and means nothing. If you truly have battery drain then download wake lock detector or better battery stats and see what's eating your battery. But you really need to let your battery set in a few days before you start getting worried about if you truly have battery drain.

It's been correct on my previous LG (Had it for a few days before exchaning it for a new one due to heating problems) This one was also displaing it right until I switched from DALVIK to ART. After I switched back, I was getting a major battery decrease. Was also doing it with the other G3 (In the process of sending it back) so I left them both alone and eventua;y the estimate went back to normal, back to about 17 hours.
ANyways, thanks for the advice
I downloaded wake lock from playstore and greenified apps i saw waking device up i have better battery life now I also undervolted -72 globably and put cpu to 12,000 something on faux clock as well as dancedance governor

[Q] How long does your battery and how long it take to charge?

hello people! I write here to learn about the time of the battery life and the charging time.
Mi HOX charge in 4 hours and the battery drain in 6 or 7 horus of normal use(whatsapp, facebook and mail app).
Salute.

Why does it actually take so long to charge? Mine also takes like 3-4 hours from 0% to 100%.
I don't charge mine to 100% or let it go under 20% but it still takes hours to charge. It usually holds
1½ hours screen on time.
Last 2 Days.

Battery life
If i install Android Revolution HD 33.1 and Alex 2.6 pa3 would i get much better battery life then viper 4.1.1 with Alex 2.6 pa3?
I see in gsam battery monitor that app usage is often at 80-90% and screen and phone radio the rest.

Solved: Is this normal??

i m on stock lolipop and my phone is 11 months old... problem is that when my phone reaches 10% charge left it drains abnormally quick and fast like 1 % in one minute and oftenly it decreases from 10 % to 5% with in one minute... any suggestionss??

Two days ago.. bt this issue is there
The battery meter is just an estimation of battery life. It shouldn't be expected to be that accurate (within a few or even 5 or 10%), nor should you make a habit of draining your phone to below 10% anyway.

thanks for your reply but i managed to solve my problem ... i wiped cache partition and performed soft reset for two minutes.. and now battery indicator is fine enough and i m getting 4.5 hours screen time with 35% brightness and locations are completely turned off. (Fck you google) and standy by time is much improved as well.... 1% battery drain in 2.5 hours on standby...... i m one stock lollipop .. unrooted as well... quite satisfied. now... i m happy to go for htc and not samsung because they have drastic problemss with lollipop

[Q] Terrible battery life all of a sudden?

A couple of days ago, my battery apparently decided to go to ****. I used to get to 4 hours of screen on time (although most of the time it was closer to 3.5), and still have power on at like, 10 at night. Now, It's on 25% with 2 and a half hours on SOT (I used it for about 2 hours when I woke up, and it had about 60% on it after the 2 hours). So, in about 6 hours, it's dropped 35% with very limited usage. I have Greenify, and Battery Doctor, so I'm not sure what I should do? Any tips? I think there might be an app running in the background which is using it all, but the apps I have aren't doing anything? Any tips/apps I should try? It's only 6 months old too.

Strange Battery Drain - Guru Opinion Needed

Hi guys,
I got my phone yesterday. But I've noticed my battery draining a bit. So far I got the following turned off: bt, wifi, data, location. Airplane mode is turned on. I disabled several apps and switched to dark mode. I got 86% batt. Last charge was 11 hours ago. I've played asphalt 9 for just 4 minutes, played yt for 10 minutes, browsed the net for 20 minutes and checked my email. Thats it!
On my samsung a70 I get 4 days without a charge. So why in gods name if I havent used the mate 20X intensely do I have 86% when I should have like 94% batt????

Appreciate the reply. The A chip has nothing to do with it. Considering the features I turned off from what I said in my last reply, the phone should be able to save batt. I'll give it a few days as a test to see.
BTW what's your batt profile and sot? How many days do you go without a charge? Are you a light or heavy user.?
I'm a light user. I last charged on Sunday night (5 days ago) and I currently have 30% battery left.

Hi gtchs,
As a light user what do you do daily to achieve this batt stat?
