Du battery saver is using a lot of your battery. Get rid off it. All battery saver apps, except for greenify, use more battery than they save.
Edit, also Google adaway if you're rooted. You need an add blocker

Yeah, never ever EVER use those "battery saving" apps, speed boosters and such, all they do is bloat up your device.

There are 2 apps I've used. Spare Parts and CPU Spy.
I found a good one after all and was able to control some hogs. Android Assistant breaks it down nicely.

Try Battery Monitor Widget [3c]
I prefer not using an app for that
i think it even drains more your battery
And how am I going to know my battery temperature?

You say that as if it is actually important
Sent from my GT-I9300 using xda premium
Use battery monitor widget as recommended above. You can even set alarms to go off of it is over a certain temperature. Don't worry it won't significantly use any battery itself. It only logs what the phone is already monitoring in the background.
As to why it might be important, well prolonged use of the battery at to high of a temperature will dramatically reduce its life span.
Plenty of us live in countries where it could be an issue. For example if I use it as a GPS in the summer on my windscreen it will soon get too hot. It's good to know if I'm running into problems.

The battery monitor says that my battery life is good! Is there a problem with the battery? Shouldn't say very good

[Q][P710] Battery capacity too low

Hey guys! Few hours ago I have installed CPU-Z. When I was reading about battery stats i noticed something strange - it shows battery capacity 1500 mAh. Is it normal? What's wrong? Otherwise it explains why my device is switching off after few hours by normal use. Some facebook, sms, calls, music... nothing special.
My p710 is running on AmigaROM V3 with the newest airidosas kernel 3.4.5. Can someone help?
Sent from my LG-P710 using XDA Free mobile app
Hmm... I use the same ROM but with the older kernel (3.4.2) and it has actually a good battery time. Probably your problem could be kernel related? But i seriously don't know the problem, however I hope I can help.
Sent from my LG-P710 using XDA Free mobile app
It's not caused by kernel I think. Not on such scale. I can't use almost half of my battery. I'm trying to recalibrate it (charge it to full state while device switched off and delete batterystats then). I hope it can help. Any other ideas?
Well, it could be a bug in the app, because our phone doesn't measure capacity of the battery, only voltage.

Its same on mine phone and i m not using rom
Sent from my LG-P710 using XDA Free mobile app
So, what should we do? Over 2400 mAh and my device is switching off after few hours of use. I've done recalibrate, my battery keeps longer but it's still not enough.

This is probably what battery driver is missing. It's no big deal.
Sent from my LG-P710 using XDA Free mobile app
I didn't undetstand. Can you explain it?
Sent from my LG-P710 using XDA Free mobile app
Battery driver can't calculate nor measure capacity, that's why CPU-Z shows 1500 mAh (on most low-end phones it will show the same capacity)
Sent from my LG-P710 using XDA Free mobile app
Okay, I see. But is it about calculating capacity only or it impacts on how fast bettery drains?
I installed Purified ROM V2. It's time for test it on performance and battery drain level.
Calibration is what determines, how quickly every percent goes out.
