Your Galaxy S3 battery capacity after three years

Hey Folks,
It's been more than three years since the phone was released. Many would have replaced the battery similar to stock or higher capacities.
Let's share the battery life and usage of our phones. I have attached snapshots of my phone from GSAM battery monitor app. I have installed a 4400mAh Anker extended battery.
Please share yours. Cheers. :good:

Hi! Mi S3 has three years as well. You can see the date that it was built with the app Phone Info-Samsung- in the playstore. Mine it has a stock ROM, and with heavy usage (games, chrome and youtube) (didn't change the battery since got the phone), it gives 3h and 30 min screen on time. Very well to a phone that have three years. Greetings.

Stock battery 2 years plus
Offline Manga reading 5Hrs SOT
Online browsing 2~4hrs
Online streaming 2~4hrs
Gaming 2~3hrs
:C

3 1/2 years
Using Lollipop it drains in 4 hours of moderate using.
Using KitKat I can use the phone for 6 hours of moderate using.

I have been using my S3 since 1 year and 10 months and can go for 6-7 hrs with heavy usage

I bought my S3 in Sept 2013 so it has been close to 2yrs now and I have switched to Zero lemon which is 7000 maH monster..it lasts me for 3 days easily with super heavy usage...if I keep it in stand by it can last me for 20+ days without any issues...

I'm still using the stock battery. I've another stock battery as spare.
So far it working well with average of 7-8 hrs battery life with light usage.
Recently, I just use the Battery Repair app to repair some bad cells in the battery. Hopefully it will prolong the battery life a bit more.

I changed recently to original Samsung's 3000mAh and would recommend it everyone who hesitate :good:

My S3 is now my second phone, so fairly light usage. Stock battery, 3 years 2 months old. Flashed Belokta Note 4 rom 5.1, Boeffla kernel 7.9. Greenify and Amplify. Able to achieve 2.5 days off the charger and 1 hour 15 mins SOT. Wi-Fi whenever possible. Not bad for a 3 year old battery and great work for the developers.

Wow, excellent score, seems like I need to try Boeffla

What are the possibilities of a phone's perfomance related to battery?

I bought my note 3 back in 2014 January 2, until then never changed the battery for once. I did bought a new phone and it's lying around in my house. THe phone's battery was weakened to this point where just booting up the phone takes ~15% charge. And if I browse Facebook with Mobile Data(4G) then 10% drains in under 5 minutes.
Also, if I play games like "Clash Royale" my phone turns off automatically(also phone heating up quickly) despite my charge is around 70-80ish
Are all these reasons due to my weak battery? I flash my phone new rom every 3 weeks.
Galaxy Note 3 SM-n900(exynos)
Update: I'm using a custom rom, is this why it is showing A9000? And if I recall it correctly, Note 3 battery comes with 3200mah battery why is it showing 2550mah?

After 3 years your battery loose about 50% of it's original capacity so I recommend replacing it anyway.
Every time you flash a new rom (why are you doing that?) the cache is rebuild which takes some time and drain your batter a bit (in your case many bits).

get a new battery and flash roms with 100%, you will be good

Thanks for the response fellas. I ordered a battery from Ali-Express, gonna take a month to arrive here.

Battery life opinions

I'm thinking of buying HTC 10 EVO but almost every battery review says that the battery life sucks. How much SOT do you guys get and under what circumstances?

nope, i think is not so bad. At regular use 1,5 days no problem.

3 hours tops on a long day., livable. Mine spent three of the last 11 months at HTC for repair... Avoid this phone if you can.

Not sure about best ROM yet but I can vouch on the stock 10.3.5 no root and 2 days into my new phone, I've got the highest battery life on Android yet over the years just by using the Redmi Note 7.
Saturday, I got a whopping 2 days of full use (radios on, YouTube videos, 1.5 hours of calls, web browsing, social media, taking pictures etc) with 10.5 + hours of screen on time a single charge!
I couldn't believe my eyes at the end of the night when I finally put the phone back on the charger.
See the screen shot. This battery in the Redmi Note 7 is awesome!

Stock rom..I am setisfied

Redmi Note 7 is a nice phone but for sure not a battery phone. The 11 days of battery life of my last phone, Vernee X Pro, are nowadays a mirage

My battery only lasts for 6h only

Hello everybody,
I bought redmi note 7 from 6 months ago.But my battery lasts only for 6-7 hours sot.
I use the old rom miui pro 9.4.11(extreme debloated)+Sys config patcher+lkt.
I want to know the best rom in battery for redmi note 7.
My usage is social media apps and calls only and performance is not important.
Please help me

When deepsleep work correct there are no significant changes between roms.
It all depends on screen brightness.
Its big difference if u watch YouTube on wlan in dark room cost ca. 8%/h akku or using gps navigation on lte in the sun cost up to 15%/h

Mine last a lotnlonger than that, I have about 6 hours gaming + some web browsing and other stuff = 9hours. If normaluse and maybe 2 hours gaming the battery last about 1.5 day - my phone is about 2.5 years old now, but I just got. new original battery.. I suggest you take it back to the dealer or go to authourized MI service center and get the battery checked, if faulty theb they can change it on the spot. NOT MI shop, they don't do service. Do NOT buy battery online(they are ALL fake), Xiaomi don't sell batteries online, it can ONLY be purchased in their service centers + fee for replacement (if not in warranty).
