The actual battery is 4000mah but the my galaxy a51 drains very fastly I like samsung A51 but facing battery issue please release for battery update.Not only me facing the issue so many galaxy fans r waiting for update.
if you not done yet then do some settings to save more battery life and observe for next 1-2 days, it will give a noticeable difference
1. Connection>more connections settings> disable nearby device settings 2. Location>improve accuracy >disable A. Wifi scanning B. Bluetooth scanning .
3. Device care>battery >power mode>select "optimised" and "adaptive power saving".
And then click on "app power management > And enable these 2 options. A. Adaptive battery B. Put Unused Apps to Sleep.
4. Long press on each app specially 3rd party(LIKE FACEBOOK, YOUTUBE) and rarely used apps and also ON "GOOGLE APP" as well, then click on>app info> then go to these 3 options below on by one
A. Mobile data> allow background data usage>off
B. Battery >allow background activity >off
C. Notification >disable unnecessary notifications like promotional and unnecessary reminder notifications.
5. Go to settings >apps>search "weather" >click on settings icon right side > change "auto refresh" settings as per your requirements and disable some unnecessary reminder. ( due to auto refresh it continuously consuming battery?)
6. If you use Facebook frequently then disable "auto play video" And if you are mostly uses mobile, on wifi connection then also disable "auto play videos" in YouTube.
I was also facing same issue but after recent update my phone seems to be normal like I can easily use phone more than 24 hours in sigle charge I also tried above steps were helpful for battery life.
after update 2.5 the battery performance was good. 24 hrs in single charge. when i update the play store apps battery is draining very fast. 5% drop in just 2 to 3 mins of normal usage.
