I'm using samsung galaxy s4 lte int. Version. Recent months, my phone battery drains at a shocking rate.. here some photos attached... can anyome help me??? Thanks in advance...

Welcome to Android Central! Sorry, your images weren't posted.

Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:


1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

Mine just started doing the same thing. Used to get 3-4 days without a charge now it can't make 8 hours. Bought a new battery and it does the same thing.:(

Welcome to Android Central! Two things that are notable about that battery graph:

1. Your cell signal looks middling to poor, which can increase battery drain, since the phone expends more energy trying to maintain the signal.

2. Something is keeping the phone completely awake, even though your screen is hardly on. Use an app like GSam Battery Monitor to find out what's keeping the phone awake all the time.

Thanks so much for the look-see! I'm afraid I'm treading in shark-infested waters though, I see that apps use 50% of the power but I have none running in the background although this System UI using about 20%. I don't know what that is. When I went to see what was going on it wouldn't open and prompted me to Force Stop, which I did and then lost my wallpaper. HmmmAttachment 229040

It gives a better picture if you look at the stats after the phone has gone from 100% down to around 20-30%. Also, see if GSam can tell you what's keeping the phone awake (look for an option to show wakelocks).
