Battery Life woes - battery management - Samsung Galaxy A71 5G Questions & Answers

Ok, so to give context, i work from home and stream either Sirius or Spotify or AMZ music most of the day. I am on my phone with Social Media alot as well so I know I am high usage. BUT, this thing STINKS at Battery management. I am coming from a Huawei Mate 10 pro. had it for 18 months. During this same usage, I would have at least 70% battery left by Noon. ON my A71, it is 50%. sometimes worse.
I will Say, the Huawei was BRUTAL on apps and really did a good job shutting down FB and other apps after I was done with them. How can I get this on my A71? I havent been in a sammy phone in 4 years or so.
It just feels like this phone uses more power doing the same usage.

I had similar problem, its battery life just on par to my 2 year old vivo nex....not sure if it's the battery problem, or their battery life management just sucks...

[Q]Mango Battery Life?

All right, so here's the big question. Okay, one of the big questions. For all yous who have DL'd and installed the Mango beta, how's the battery life?
I have a NoDo'd DVP and I generally can get 9 and a half to 12 and a half hours on a single charge depending on what I'm doing. Games being the biggest battery vampire I've found, thus far. Streaming vid a close second (perhaps tied).
Can't tell any difference. Never been an issue on my Arrive. It says I have 16 hours left(with battery saver kicking in if it gets critically low), and it has been 12 hours since my last charge.
I play a few games a day. Some web. Music. Testing of Mango features. Getting features to work. Lot's of texts. And my 3 email accounts syncing frequently.
I do have wifi disabled as that was preventing speech recognition from connecting to MS servers for some reason. So that may have improved battery life a little.
Good to know. Figured it would be about the same. The real test is how it will do once the LTE/HSPA+ devices hit.
I'm actually noticing better battery life. I definitely have been playing with the phone a lot since Mango, even more than normal, and the battery has been pretty awesome so far. Course its not scientific, but it appears that I'm getting more hours out of it than pre-Mango.
I think it's better in Mango but it's hard to say how much and if any better at all. If I had 2 windows phones I'd love totest it to find out.
Anyway I'm really happy with mango, I have to stop using facebook chat or I'll not get any work done today!
the battery life is better,just remember that multitask is in now
In previous version you don't have it
In my situation (lg optimus 7) battery life seems a little bit shorter than NoDo...
I turn on the phone in the morning (8-9 am) and I've to plug in for charge at night (11pm-12am)..
I've 2-3 live tiles active in the home screen... with NoDo i Could permform 1 and a half day of usage... I think this is a mango bug, or my battery just need a recalibration for the new O.S.
I'll check it in the upcoming days
I feel like my battery life has gotten worse, but I have 4 live tiles running and facebook chat on, although I had the same on my nodo device save facebook chat. And I think the battery saver option basically just allows you to turn the feature off. Wasn't the whole stopping push notifications done automatically in nodo when the battery was low? Now you just have to option to disable and kill your battery faster.
Hmm, I too have the feeling the battery life is worse. I just recharged to 100% and battery saver says I have 23 hrs left. After 1 hour without doing anything I have 80% (17 hours) left . I turned on airplane mode and disabled location now to see if it's getting better.
I also feel the battery life got worse. However, remember this is a debugged build, it's logging alot more as you are using it and I'm sure there's still alot more optimizations to go.
With that being said, I'll gladly take 2-3 days instead of 3+ days on a single charge for the features added. For those only getting 12+ hours, somethings wrong with your phone. There's not that much more getting executed vs NoDo until more devs take advantage of background services and live tile updates.
Hmm, yeah maybe my battery is quite exhausted already. I use the phone daily listening to music at the train, playing a game or two and browsing. That is, I recharge every single night and sometimes again in the afternoon. So I guess I have recharged the phone ~300 times since I purchased it last year.
Overall, better. I did opt for the 1800mah battery for my Trophy and it did help a little (keep the OEM one always charged, just in case). I think it works better
Its quite a bit better for me. I can usually go through a full day with battery saver generally kicking in near the end of the day (9-10pm). Bluetooth headsets for music does kick it down a bit but not terribly, usually my BT headset runs out before my phone.
Focus/mango.

Interesting, I knew back in WM 6.5 using a BT headset would take a 12 hour battery and make it last no more than 6 and that was if you didn't talk on the phone much.
Is Bluetooth better with WP7 where it's a very minor battery loss ? ( might pick up a new bt headset)
Mine is better. But only slightly. Eg. 45min to 1 hr better.
I'm using a Focus

how do u know that its doing logging??
if yr sim card is more than 2 years old y will experience battery drain
There is definitely a bug in battery saver
There are to things to think about: The first one is that we have update our phones to Mango, but not the manufacturer so we have old drivers with new OS. And the second is that at least I, i've been so far 8 months with my HTC Trophy so the battery also losses capacity (mAh) in this time. In 1 year usually a battery only has 80% of its original capacity.
I have actually feel the better battery life.

Owners: How's the battery?

XZ Premium owners, how are you finding the battery? My Z2 and now Z5 have never guaranteed me a full day, and now that my Z5 is a bit older I'm charging twice daily. So I'm torn between the Z5P and the OP5, for all it's flaws -- is battery life better than the Z5? I'm particularly interested in dual-SIM, but I assume the battery life won't be all that different to the single-SIM handset.
My last Sony phone as a daily driver was my Z3. Battery was fine on that until I did anything that made the CPU go into meltdown.
On the XZ Premium, Sony and Qualcomm have got things nicely under control - which means the phone doesn't run too hot (which in itself plays havoc with the battery, and can make it near impossible to charge) - and the battery doesn't seem to take much of a hit even when playing video or taking photos.
My phone can still get hot when taking photos and give me the warning, but despite me using the phone heavily, the battery (given its size) works commendably. Especially if you enable any of the stamina modes
I could live with most of these modes enabled all the time, with the only issue being when using an on-screen keyboard (it missing characters pressed), and then the battery lasts even longer.
tl;dr - the battery is good and I'm very impressed. You should get a whole day of usage without fear, and with a good deal of screen-on-time.
I got this phone yesterday. My previous phone was the Z3 Compact which was the king of the battery life back then, but now i think the XZ Premium is better than the Z3c while i use certain apps and it consumes more battery only when i use the Camera, Photos app, Video app and Youtube. I haven't used Stamina Mode yet.
Mine battery life is good, my best was 31 hour running always under 4g with 4+ hours of screen on
I do a day and a half with every single charge at the moment
Thanks everyone.
@Katsigaros, could you let me know how you're getting on after a week or so? I don't plan to buy until the start of this month, so I'd be interested in progress.
@Tonyevol that's impressive for standby, but is 4 hours SOT good? I had the same response from a few people on Reddit, with 5 hours of SOT, but I though 6+ was kind of the norm these day, with good phones getting 7 or 8.
I am getting 5-6 hours SOT as of now. Over a month, I have seen marked improvement week on week. Once we get root/ twrp, we can disable some processes and programs that aren't required thereby maximizing the battery juice.
Little better than Galaxy S7 Edge which is my previous before. I am quite happy with battery.

After the first time I used it i performed a full recharge from 1 to 100 % to calibrate the battery. I am watching a lot of videos and because of that the battery lasts me 1,5 - 2 days. If I am not watching videos I can get almost 3 days.
I will have a clearer view on battery life after one month but right now I am very satisfied with it.
It depends a lot about the way you would use it. For example I'm all days around without wifi connection avaible and of course 4g connection all the time working drains a lot of battery juice. Also having Facebook running all the time with instant messaging always on makes differences. Without using Facebook and limiting display luminosity would grant a much SOT

SOT-Battery Life

i´ve been using the mate 9(l09) for about 9 months and at the start the battery life was the best i had experienced in a smartphone, after a month the battery life was noticeably lower(4hr 30min hr sot) that when i got it. i was on some weird latin firmware(mha-l09c212b181) and rebranded to l09-C432B198 hoping to get more sot but only got about 10 more min.
Any suggestions of firmware?or should i replace battery? whats your experience?
What's your daily usage like?
Maybe you've installed a rogue app that's draining your juice?
Been using my phone for a year now and I still hit 9 or 10 hours of sot.
YMMV, i would trace back on what app you installed before the whole issue occurred, if not worst case scenario is to hard reset everything, make sure to back up all your stuff.
If no change then either your usage habits are greater than when you got the phone or a defect in the battery
One year using this phone and Im still able to get 9 to 10 hrs SoT within 2 day usage. I used fb and fb messenger a lot (4-5 hrs), web browsing + video (2-3 hrs) and of course 2 hrs of playing games. It's still a beast for me right now, no phone can replace it, maybe mate 10 or other Kirin chip phones. For me, Kirin is extremely good in managing battery and multi task, my phone is always smooth and fast as hell lol
My phone is so much better on Oreo battery life.i don't know how you get so long sot other poster are you on wifi with good cell reception all day.
. I get around 5-6 hours
Been away for some time son no time to reply. im going to factory rest on the weekend and only install the basic social media so i can get more SOT than im getting now. If this works ill install apps one by one and see if one is draining the battery. Otherwise i will concider a battery replacement.
anyone know a better way of tracking the apps that drain battery?

Got a new Pixel. Battery Life sucks. Is it normal?

Hello,
I've sold my S7 and bought a Pixel phone because of updates and design. It is very elegant phone and very very fast. But I've got a problem, battery life sucks seriously.
Here's some screenshots.
Because it is a new Pixel, don't think there is a faulty. I did Geekbench 4 battery benchmark and got 1700-2000 points and got over 162k Antutu.
Is it normal? Should I roll back to Nougat? Or else I will send it back and Pixel XL. I cannot afford Pixel 2 or Pixel 2 XL.
Rolling back to Nougat will do nothing good. Did you buy a new Pixel or an used one?
Same here. Bought a used Pixel 128 GB model last week that provides only 3 hours of SOT with normal usage (browsing, music, videos).
It's on Oreo 8.1 with latest security patch and NFC, location turned off. Still no good.
Excluding gaming, for chrome browsing, reddit, YouTube and Instagram plus a few other misc apps, I get approximately 3.5 hours on data and 4+ on wifi. Rma brand new set from Oct 17.
SD 820 is not really known for its battery efficiency vs the 835.

Your first 5 apps listed are using about 50% of your battery. On my pixel XL I could easily get 8 sot if I wanted. You should look for ways to reduce battery useage, like battery optimization and limiting power to apps not in use. What does the acc battery app say your battery health is? My battery preformed better after installed dp2, but was very good before installing dp2, it just got better.
I've got 100% battery health. Now I get 3-4 SOT, 10-14 hours standby. It is not the best, but it's ok.
How can you limit power to apps not in use? You mean deactivating background process? I did that already.

That doesn't sound particularly bad. I normally end a day on about 20-30% with 3 hours of screen time or so. I know it's a bit of a cliche, but it really is hard to compare two setups like for like. Even SOT is not a great measure because if you watch a 2 hour downloaded movie on Netflix with low screen brightness (for example) that will consume A LOT less power than playing a game or browsing the web for 2 hours... but both will just show on battery stats the same. Let's not get into whether you are a user of Google location services (for things like Google fit or Assistant etc), or streaming Podcasts over bluetooth...
Some people have already reported better battery life on Android P - though I take that with a slight pinch of salt as every Android release supposedly did that already.

Question S22 ultra bad battery life

I'm interested in the battery difference between iphone 13 pro max and s22 ultra. I now take out with s22 ultra 5-6 hours of screen on time max but in fhd +. If I play pubg, it takes 3 and a half hours without stopping. Is the battery difference so big for the heavy user? Can someone give me some screen statistics on time in heavy use, in games but also in normal use youtube, instagram, fb ... I'm thinking of returning s22 ultra and taking 13 pro max because I'm not very satisfied with the battery s22 ultra. But if the difference is 1 hour then it's not worth the exchange ... I am very dissapointed. I paid $ 1500 for a phone and charged it 2x a day. I do not agree to compromise at 1500% I want to receive what I paid. 120hz -wqhd ... I barely have 5-6 hours screen on time with all apps in deep sleep, 30-40 brightness, fullhd +, location off, 5g off .. Is there any solution ?? this is the exynos variant. Except for the battery, the phone is superb.
I get 14-16 h of total battery life with 3-4 h screen on time, not a heavy use, just some light web browsing, mostly Google Now feed, as well as 2h of Spotify over Bluetooth

I get similar results using the exynos variant. My phone uses 20-25% battery per hour for things like social media (Instagram, TikTok, Snapchat) and browsing/YouTube (FHD+ 120fps). I've seen people getting more than 6 hours screen-on-time with S22 Ultra, but I don't understand how they achieve it. The phone is great, but I am pretty disappointed by the battery life.

Thanks for the confirmation. For me, it looks power consumption optimization issues, either hardware, software, or both. Let's hope that software optimization helps in the future

The thing is that I've been using an S21 Ultra until last month (for the last 5 months). Its battery life was similar with the S22 Ultra I am using now, but slightly worse. I was intrigued by such poor battery life and I brought it to the Samsung Service (device was under warranty). After 2-3 days of service time, they fully refunded my S21 Ultra and I upgraded to the S22 Ultra. I really don't know what to think now, if this battery usage on my S22 Ultra is normal or if there are any problems with it....I can get with it through one day, but, again, I am intrigued that others are getting much better battery life results than me (about 10-15% per hour of screen-on-time).
I think most people on here are getting better battery life due to app usage, debloating, deep sleeping apps and dark mode with amoled wallpapers. I also believe that the device care doesn't give accurate screen on time. Sometimes i would use my device for 10min and when i check screen on time it doesn't refresh immediately.
We have to remember that this panel is brighter and a lot more vivid that what we've had before.
My suggestion if you're not into doing a device reset. Uninstall and then reinstall your apps.
I did this with Facebook and i have seen an improvement. Also i keep seeing apps that are recommended for sleep due to high battery usage and you wont believe some of the apps.
Guys, just monitor and keep all your apps up to date.

Going through your apps and weeding out those that burn through your battery is very important. As an example, I was using Google News app perusing some articles for about 30-40 minutes. Since I use DuckDuckGo with app tracking I later found that during that 1 session the Google News app sent 1401 tracking messages behind the scene. Lots of apps do these types of things and more, especially social media apps.
