I have got my s7 edge about a month and a half ago, the battery was amazing that it woulf last 12 hours off charger with 40 or 50% still on, now as soon i unplug the charger, battery starts draining one percent every 3 or 4 minutes. I tried wiping cache off, and uninstalling apps but nothing seems to solve it.
battery stats always shows that screen is consuming up to 45% of battery life. Please help what can i do?

Welcome to Android Central! Is the battery draining that fast only while the screen is on? If so, that's normal -- 1% decrease every 3-4 minutes means 300-400 minutes of screen-on time, which is 5-6.5 hrs.

Screen will always be the top battery consumer if it's been on. If your screen hasn't been on and it's still taking 45%, then I agree that would be unusual.

Show us some battery stats. 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.

Is your brightness set to a high level? If so, you should probably slide the brightness down lower. Is the always on display on too? That can also drain the battery, although only about 1% every hour.
