[Android Central Question]

I updated my Samsung around 3 weeks ago and now j can get around 3 hour battery life if left on. Without using it much. Have cleared cache, ensured I use a Samsung charger, closed draining apps etc, lowered screen brightness. And when I check battery usage the orange icon of 'screen' is by far the most. Is there anyway to troubleshoot this? Also android idle, Android system, cell standby and cell idle are in the top 8 apps. How can I turn these off?

Welcome to Android Central! Which Samsung phone? What was the system update for? If you're actively using the phone, Screen will almost always be the top battery user, since it takes a lot of power to light up those pixels. If Cell Standby is relatively high, I'd suspect the problem has more to do with poor cell signal, which is notorious for draining battery.

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).

You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.
