Rather than clogging up other threads with my battery experiences, I thought I'd summarise where I'm at, and see how other people are doing with their battery life.
So I started yesterday on a full charge, and by 2ish the phone was dead. I used it fairly heavily, but wifi was off. I don't think I made any phone calls, and didn't use gps. It was mainly messaging and using the xda app. I had changed my screen brightness to auto the night before, so thought this might have reduced the battery life.
I then left the phone off, and charged through till just before 5pm. At this stage, the phone was up to between 90-100% charge. My intention was to see if I could get through to this afternoon on this charge. Last night I made a phone call for about half an hour, and used gps for about 10 mins driving in the car. Other than that it was a bit of messaging and browsing, but not heavy use by any stretch of the imagination. I had wifi off, facebook sync every 4 hours, and screen brightness set to about 50%.
This morning I woke to less than 10% charge on the battery, so have left the phone at home charging, and I'm back to my hero...at least for the morning.
I must admit, I'm starting to get concerned, because I really don't think I'm using this phone more than my Hero, and I could easily get a day out of it (unless I was going for a long run using some kind of gps app).
What are other people's experiences? I'm surprised I'm not hearing more about this, and I'm hoping mine is just a one off!
**UPDATE**
Today, 12 hours after taking my phone off charge, I have just under 20% charge remaining. The phone is now on it's fourth cycle, and although I haven't used the phone quite as heavily as yesterday, I have still used it quite a bit and have had WiFi on the whole time. This is still not amazing battery life, but it is still much improved. It definitely illustrates that the battery may take a few charge cycles before it optimises itself.
My first full day was yesterday.
WiFi on all the time. Screen brightness set to automatic. Twitter and facebook refreshing every hour. Weather every 4 hours.
Unplugged the phone at 7am, 100% charge.
During the morning I flashed the phone twice (due to the proximity sensor issue) so it probably recieved an extra 10 mins of charge.
Following the flashing, WiFi went straight back on so I could download all the apps again, and resync sense and all the contacts. There was some playing of games, some use of Google Goggles (so camera use there) and some web browsing.
By 13:00 I was down to 90% battery - which was pretty good I thought.
Through the afternoon I didn't get to use the phone much apart from a couple of short gaming sessions.
By 17:00 I was down to 80%. I got home from work and played around on the phone until my wife got home and we went out for a meal. The pub we were in had no signal, and I didn't really play around with the phone.
By the time I got home and went to bed, the phone was probably around 65% full.
So not a heavy day of use, but not far off a standard day for me - so not too bad as far as I'm concerned. Certainly about 30% better than my Touch Pro2 was!
I think we need to define a consistent way to measure battery life for Android.
Something like ACID test for web ... Quadrant for benchmark ...
I don't know, maybe we can agreed on something how to measure it. Or build an app to simulate phone usage which user should run it continuosly and then at the end got the result: Your battery life is rated 4 hours, 10 minutes straight using this test.
Probably not the best measurement, but it should give us a "number" to compare with other devices.
I can only suggest (I am not a developer), but I believe there are a lot of talented coders here in XDA which should be able to build this kind of "standard" app battery measurement pretty easily.
Somebody is recommending 3-4 full charges cycles for battery optimization. Do you think it will really help?
Battery is really deal breaking issue for me.
very helpful thread.
as mentioned few post earlier, there really should be a battery benchmark tool.
so was your wifi and/or 3g turned on the whole day?

My friends also lasted over a day with pretty good use, there seems to be better results with the brightness on auto...from what I have picked up on the forum...maybe a test is need to see how much difference there is between full brightness on one battery charge and auto on the other.
Yupe, the battery benchmark should not be so complicated.
Start the app with 100% Battery life
Some options in the app (for features that might NOT be in an Android phone or might not be available at the time?):
[ ] Turn on Wifi
[ ] Turn on GPS
[ ] Turn on Bluetooth
Set the app to WAKE all the time, display turned ON all the time of the test
Set Keyguard to OFF (device will not be locked)
Set Brightness to AUTO
Set all speakers to SILENT
Set vibration to OFF
Then loop until battery down to 5%, perform the below tasks in sequence:
* Play movie for 15 minutes [speaker muted]
* Browse to website??? be careful not to overload the website
* Doing arithmatic
* Doing 3D
* Play MP3 [speaker muted of course]
As soon as the battery down to 5%, app stop and display result ...
And of course restore all the settings.
The app should use generic API that is supported by Android, not some hacky wacky if you know what I meant.
Please if someone can code this, that would be very nice! Standard XDA Battery Measurement app for Android!

the app should log the result too.. since some phone is dead by time 5% due to calibration..
@Dazultra2000: I would almost trade the proximity sensor problem for the battery life you're getting!
In any case, I'm gonna leave my phone charging till half an hour after the green light comes on, then I'm gonna try another day of normal usage. I'm going to turn wifi back on, as I usually would, and set screen brightness to auto.
With my Hero I used to go for runs using a GPS app to log the route, I'm not going to bother trying that with this phone until I'm sure I can survive a day.

I don't know when you wake up but that could be like 14 - 15 hours that you mentioned which possibly isn't all that bad (plus the extra 10% you had remaining). Personally I want to see what it's like when you unplug it at 8am, not at 5pm the night before since I can't see any good reason not to leave the phone charging over night anyway.
If you then manage to get about 10 to 12 hours or so then there probably isn't much issue. Granted you weren't using it while asleep so the battery shouldn't drain overly quick but I wouldn't want to use your test as an example of a days use.
Thanks for the info but. If I was you I'd just have a car charger too if you like to use GPS...I can't see any reason not to.

Yeah, I would normally charge overnight, but since I had given a charge through to 5pm I wanted to see how it lasted....see if I could get through 24 hours. I wake up at 5am, so that was around 12 hours, with only 5-6 of those hours being time when I would've actually been using the phone. This is also bearing in mind that I had started yesterday on a full charge and the phone was dead by 2pm.
The GPS thing in the car was only to do a quick test, literally 10 mins. I need to buy a new car charger with micro USB, but I just made a note that I had done this because I knew it would affect the battery.
Anyway, we'll see what today brings.

Looking forward to it.
And yeah, for me personally a "days" charge really only needs to equate to about 12 - 14 hours. Thats probably the longest I'll go without having a charge anyway unless I'm camping or something in which case I'll likely fall back to a Nokia anyway.
Hi, just to add my experience with a complete different phone e.g. iPhone 3GS (developing apps on it, now switching to Android ):
Charge at night till 8 a.m. so 100% then usually in a day:
- Go to office, read/write emails, surf a bit on forums, blogs and so on
- Make call up to 30-60 minutes per day
- Play some games, test our application/games on it (so connect and receive some extra charge)
- Use WiFi at office
- Use Google Maps up to 15 minutes per day
- Back at home at 8 p.m.
- Use again emails and surf on web for 30 minutes
Around 11-12 p.m. it has less than 25% of battery, so 14-15 hours of usage drain battery up to finish it, not to mention that I'm forced to switch off push notification because they drain my battery in 5 hours!!!!
So just to say that, no one is perfect, and this devices today really do a lot of stuff, I think as Smigit suggest 12-14 hours are acceptable.
Have also tested/used iPhone 4, I don't seen any big improvements on that side.
Just my two cents...
praying for decent battery, please please please!
My HTC legend is pretty poor really, but I can live with it. If DHD is worse I don't think I can pull the trigger.
There is a thread in th Legend section about 1800mh HTC batteries (from another phone) that fit the Legend. Maybe there will be an option to do something similar with DHD.
I would pay £50 more for a 1500mh battery - why did they put the smallest battery in the largest screen?

No the battery doesnt fit with the Desire HD, if you watch some pictures of your 1800mah battery and than go and take a closer look at the DHD's battery, you will recognize that the pins of the DHD-battery are on its side. the pins from the Incredible Battery are on the bottom.
In 2 hours 30 min heavy heavy heavy use, the battery dropped 20%.
Will do a full day test 2 morrow.

My battery stats
Hey there!
I bought this phone on Monday and I started using it yesterday. Here is a screenshot of my actual battery.
I've used 3G and Wi-Fi, downloaded some apps and used GPS a bit. Now I'm using only 2G connections and the brightness is set to low.
Very happy with it!
Just a request
When you all post battery Screenshots please mention the on screen time all of you get and if possible mention the brightness also
Addition
Mention screen on time...
Mention rom (when available lol)
If possible mention ur personal setup like u greenify apps or not...
First charge.
5h screen on, autobrightness, 1 1/2h gps and some other game testing so pretty much like the old G
Seems very solid, 5h SOT. I might be joining your community soon
On average usage it will last for one day
The battery life is better than what I expected. It has dual sim and a large screen but still manages around a day on battery.
Managed to get slightly over 7 hours before the phone shut off.
GPS: Power saving mode
Screen: Brightness set to indoor conditions (manual / below 10%)
ROM: Default
Battery Saver: Disabled
Battery saving apps: None installed
WiFi and Sync: Always enabled
Screen Time Out: 2 minutes after inactivity
Usage: Mainly Facebook, Chrome, WhatsApp, few YouTube vids and Google Docs. Nothing intensive.
Phone charged from 0-100% in under 2 hours without entering the OS. I used Anker Power IQ 40W 5-port desktop charger and Moto's USB cable. Back of the phone remained cool throughout. Could have squeezed more life out of the battery by setting screen time-out to 30 seconds, but I'm happy with 7 hours. Used to get between 3.30 to 4 hours on my NEXUS 4.
Moto G has one of the most (if not the most) efficient SoC (especially the CPU core). So the biggest improvement to battery life comes from adjusting the screen manually. Don't use auto brightness if possible and keep the brightness low without sacrificing image quality. Mine is set to below 10%.
If you have any questions, feel free to ask :good:
Impressive

WOW, that's really impressive. Yes, auto brightness can drain the battery soon. I use auto brightness whenever I'm outdoors for a couple of hours and I get 5+ hrs of usage. Very happy with the battery life.

I'm in doubt between G and the new Moto Moto X (2014)
Who has better screen time on 3G / 4G will take my money.
No gaming in this cycle of battery charge
But internet use is there over Wi-Fi.

Very happy with battery life. Very first charge, just received phone in the afternoon and was fully charged by 3:30 or 4. Downloading applications, syncing accounts, installed GTA:SA and played a tiny bit(used a controller through OTG) snapped pics, took some slo no videos and auto brightness. Texting, IM'ing, some YouTube videos, etc and also music, which sounds amazing through the speakers!
Not bad at all
Battery is not bad. I was using Wi-Fi n downloaded applications. Still I got it for 20 hrs n had around 15% left.

Yeah I was kinda amazed. Wasn't expecting 7 hours. Expect the battery to increase even further when Android L is released
Five hours screen time
Pretty good for Android phone
My new Moto G has been amazingly good with respective to Battery backup. :good: When phone is idle... it is alove for almost 1 and a half day... Amazing.. I also had Lumia 520.. It could last for 2 days and still have juice left.. Very impressed..
I find the battery life to be average, I get about 3.5 to 4 hours of screen on time. Which is what most phones get, but the original G could go for 5hours. And by about 7pm, my battery run out.
You could get 5hours screen on time if you stay indoor and connected to WiFi all the time and on 50% screen brightness, but this is not for someone who is moving about, being outdoor and not connected to WiFi during work.
Battery is pathetic...The phone was in deep sleep for 8 hours. Battery consumed while in deep sleep, was 1% per hour
What's wrong? Feels like eclair days...
Day 1 lolol just wanted to be the first to make this!!
Gemme a few days and I'll post some pics. Also include your usage, signal, and any disabled apps/services! Let's get it!!

Same here. But when i finished installing it, I fully charged it around 9pm last night and it just went to 10% today at 1pm
I'm at 4h 40m screen on time, with 36% left in the tank. I put the mid batt saver on at 65%. At this point I'm pretty impressed.

Yea I don't know what happen but my last 2 charges after that has been around 5 hrs max. I didn't do anything different. But I'm still satisfied with 5 hrs SOT
One thing that isn't mentioned enough is battery maintenance and care. A carefully maintained battery will last longer, and store more energy, therefore providing more time between charges. I have a lot of knowledge about lithium based batteries in the hobby grade Radio control models. I have been maintaining lithium polymer and lithium ion cells for about a decade. So I would like to compile some tips for everyone.
1) Heat. Heat causes the most damage to lithium based batteries. Leaving your phone in direct sunlight, as most of us know can cause your device to catch fire, or even explode. Water is useless in extinguishing a lithium fire. Lithium cells will burn under water. This isn't new info to most of us, but I mention heat mainly for these reasons;
A) rapid charging causes increased heat in the cell. This increased heat degrades the cell, causing reduced cycle life. This is significantly more concerning on modern phones without removable or replaceable cells. Therefore you should avoid rapid charging unless it's absolutely necessary. Especially overnight. If your sleeping then there's no reason to rapid charge.
2) Voltages. Voltages are also very important, but since these are managed automatically you don't need to be overly concerned about them.
A) 3.0v this is the minimum voltage at which your charger will still recharge the cell. Most phones will shut off at 3.3v or 3.2v. This is your 0% charge level. The reason this is significant is that once your phone shuts down from a dead battery it is important to recharge it within a reasonable timeframe. It may take a week or 2 for the cell to drop those last few tenths of a volt, but once it does it's over.
That said, it is good to completely drain your battery occasionally because this helps the OS calibrate a more accurate battery charge percentage.
B) 4.2v is fully charged. This is your 100% charge level.
C) 3.7v is the best voltage for cell storage. This is approximately 50% charge. That is why your phone is usually about half charged when it is unboxed. (But who stores their phone lol)
So the important takeaway from all of this is, avoid rapid charging when you can, and once your phone dies, recharge it soon after. -Chris
Not bad. Got me through the day. ~4 hrs sot
Too early to tell. I had like 3.30 SOT. After a couple of charge cycles it's getting interesting.

I went through 16 hrs of my average use and had 39% battery left before calling it a day. That's at least 30% more than what I was squeezing out my Note 4 on 6.0.1. Idling overnight for 7 hrs the battery went down only 4%.
I'm really impressed so far!

If the question is for me....yeah, Material Dark Theme. Nova Launcher, no stuff disabled (Wi-FI/Loc/BT etc.). No app power saving. Hi resolution. I run "Optimize" once in the Device Maintenance menu.
I'll post a stats screenshot at the end of the day
I don't really trust any battery benchmarks right now..... the phones are all brand new...... lets all wait about 12 months and re-check them; While compared to the Note 3 my Note 7 replaced I am generally happy with the upgrade to the Note 7, the sealed battery is really pissing me off. I was using the Zero Lemon 10,000 mah batteries on the Note 3. I can almost gamble that the battery in the Note 7 will be useless in 12-24 months depending on usage and then we are stuck with $800 bricks unless someone figures out how to safely open the phone so we can replace the battery on our own.
Yesterday I had 7.2 hours of SOT. First few days were a little less, due to initial geek out, setup, testing. Seems on par with the my Note 5 and S7e.
What this shows me, is that I need to spend much less time in front of a phone's display....

For how I use the phone, I can easily get over 7 hours SOT....with 10% or more left. Yeah... I disable all the Sammy/Tmo bloatware I can....as well as Lookout, Android Pay, Facebook stuff...and a few others. I always use Nova 3.3 (the last before they switched to the horrible white themes of LP & MM) and I've been using a minimal black theme from the Sammy store, that has the color rings around some icons. Love it. I don't use auto brightness...and normally have it about 30-40%. I also don't ever use NFC, so it's disabled. I rarely use bluetooth....and i don't do any gaming really. I imagine if you're doing those things...battery life will suffer a bit.
Though I definitely think it helps to have an all black theme going. Settings, dialer, app drawer....solid black. And don't have the screen too bright of course.
I don't know how good or bad it will be but in my opinnion it's going to be average and its a note so i'll be using the phone a lot. I just bought the wireless charging case from the T-Mobile store i work at My coral blue comes tomorrow !!!

Better to ask what usage they are doing with their device...
More than 8h on a row, meaning either watching movie / series or listening music screen on.
Which level of screen brigthness ?
Wifi, 4G, etc ...
And which running app ?

GSam screenshot explains most..
I browse a lot, chat a lot (whatsapp), some YouTube (short reviews), no series or movies, no streaming music or listening music while screen on
last post were almost solely on wifi, previous one mixed 4g wifi, and no I don't put screen time out to ridiculous minutes just to achieve sot. All this on my regular use. With similar usage, this is better than my previous s8+ exynos (6-7ish hours).
Disabled Google now as I don't plan to use it at all nor the assistant.
45-50% brightness on auto
Turn off location when I don't use it for navigation
Rarely use phone phone calls, only short minutes in whatsapp call
The battery is just that good for my usage.

No offense, it was just to share that our personnal usage are very different and affect drastically our battery and SoT.
for eg. only playing (Clash of Clan or Trials Frontiers) leads my SoT down to 3h45.
While doing other stuffs like you described allow me to reach nearly 6h SoT.
I also have a very bad 4G/LTE coverage and it affects a lot my results.
You are having very good result btw.

None taken bro. Indeed usage between each users will be different. Which is why I usually compare to my other devices I own or previously owned. My typical usage everyday comprised a lot of typing in chat apps with customers. Obviously I will get more screen on time than a person who plays game on their phones.
My previous phones sot, my typical usage: (i owned a lot of phones cuz I sell phones for a living lol)
My friends brag about their iPhone 7 plus and it's stellar battery life. But with my typical usage, I never get past one day mark without needing to top up.
S8+ was awesome, but in my typical usage of mixed Lte and wifi, it rarely goes past 7 hrs mark. On full wifi tho, I can reach 8-9 hrs of sot. This was all achieved after disabling a lot with package disabler.
Op3t: wifi 6.5 hrs, Lte 4-5 hrs huge difference between wifi and Lte
P10+: wifi 6.5 hrs, Lte 5hrs
Pixel xl: wifi 6.5hrs, Lte 5.5 hrs
HTC 10: wifi 6hrs, Lte 5.5-6 hrs
XZ premium on the other hand, my norm is 7-8 hours mixed Lte wifi, 8+ on wifi.
Typical day of streaming, texts, two email accounts and some browsing. Only thing missing is WiFi tether, as I was at home today. Much like other Sony devices I've had, battery life borders on outstanding.

Thank you mate :fingers-crossed:
Battery life is pretty good here. With bluetooth on (for the bluetooth headsets), youtube, browsing, some gaming, and talking on messenger/whatsapp, my SOT is between 6-7 hours. Compared to my old phone where 2 hours and half was awesome for it, this phone makes me more than happy with its battery,
Fantastic screen on time
I was getting about 7hs of SOT on the the first 3 or 4 days.. but now, the battery consumption is really high Im struggling to get 3..4hs.... Gonna try a hardreset.
It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy M51 before depleting the battery.
Then, drop a comment if you have anything to add!
Getting 17hrs of screen on time minimum on full charge for youtube 3hrs , clash of clans 2hrs and 45-50 mins of calls per day....last 3 days with my usage
Plus Whatsapp of 1 hrs approx per day

SS or it didn't happen
I've had this phone 2 days and so far I've had 6 hours 31 minutes of screen time and I have 58 percent battery left. This is mostly YouTube, Web browsing, an hour of downloading apps from play store and a bit of emulation (ppsspp) am extremely impressed with the battery life on this phone.
Battery lasts more than 2 days at Medium Power Saving mode with moderate apps usage(no gaming but with youtube, magic fluid live wallpaper, whatsapp, browsing) and SOT approx 13+ hours in these two days. At the end of second day battery remains at 30-35%.
Has anybody here compared to the Moto G8 Power? Is the battery life even better?

Exactly how do you think a cheap SD 665 11nm chip with a 5,000mAh battery will do against a higher tier SD 730g 8nm chip with a 7,000mAh battery?
Hmmmmm ?

So exactly how do you think a phone with half the specs will do?

You're missing the point. My post has nothing to do with that...
I'm simply asking, that if you have anything to add to a thread, please do so in a constructive manner without snark or attitude. It would have been very easy for you to convey your message without being rude or condescending.
If you've got more to discuss on this particular matter, please contact me through a private message (to keep the thread on topic).

To come back on it, I have it since today and so far it's looking like the G8 Power has better or equal batterylife, standby drain is somehow bad on the M51, I checked all apps. Still I'll let the software settle and get through more cycles and check Gsam Battery Monitor in a couple of days again.
I honestly blame Samsung's other apps that aren't used and aren't able to be disabled or uninstalled.
Hi guys. I wanted to let you know my findings and provide some test results of galaxy m51 battery life. Firstly, I will outline what was my priority for that test. I wanted to check how long the phone can last mainly on google maps navigation with additional apps in the background. Also this test is a bit static so to speak but had no chance travelling for so many hours. That said I believe SOT was tested correctly for my planned usage. I guess in a real case scenario, I would need to do some more browsing and perhaps occasional screen switch offs during a break like filling up the fuel or stop to rest on a bicycle.
How I performed my test.
1. I did some initial installations, downloaded my apps and logged in to social apps such as FB, Spotify so they can work in the background, send notifications etc.
2. Once I completed the setup, I charged the very new phone to 100%. AccuBatter reported capacity was 6800mAh designed capacity not 7000mAh and estimated capacity 6700mAh.
3. CPU-Z reported Snapdragon 730 so I regret it is not 730G and honestly I do not know how to check with online stores as the packaging does not help with this. Also, I plan to test POCO F2 PRO 8gb ram/256gb version the same way and see how it goes since I get better hardware, but I like SD card slot on galaxy m51. Very useful when resetting the phone.
4. Set google maps navigation, lunched another app which uses GPS and LTE for maps showing speed cameras, road works or dangers which I use alongside with google maps. I also start shuffle play on Spotify to imitate streaming the music in my car or on the bike.
5. WiFi, LTE, GPS, Bluetooth, sync was enabled, blue light filter enabled.
6. Between 15-20 apps were in the background.
7. I unplugged the device from the mains.
8. Initial 15% discharge was with a WiFi connection with my router. Then switched of my router for overnight, left wifi enabled on Samsung but it had to continue downloading data over LTE such as Spotify music streaming. I also changed google map setting to day light only to avoid night backlight.
9. I went to bed? and in the morning there was still a lot of juice.
10. Around 20% discharge I took about 100 pictures most of them in burst mode to simulate a trip where you simply stop and take some snaps.
11. I stopped the test at 1% discharge and noticed no heating problem. The phone was cool during the test.
The overall SOT measured until 1% discharge was a staggering 17h 50m? Below you will find AccuBattery screenshots. At remaining 15% I had still over 2 h 42 m of use left.
This phone reminded me of good, old days of my Samsung galaxy s3 with a Zerolemon 7000mAh?
Now with my galaxy s7 deteriorating battery (current capacity just over 2300mAh) this is a great thing. For Galaxy s7 I also own a KiwiBird powerbank case of 5400mAh right from the beginning wich did its job when away from the mains, travelling etc.
I guess for a more accurate SOT, I would need to add some phone calls and browsing but even with I deduct 2h, it is still nearly 16 h of use. Like for me excellent. I also do not plan gaming.
On the downside of this phone it seems like my galaxy s7 takes a bit better picture, but it just might be my perception of selfies taken. Back camera is also just ok on a cloudy day. Ok but that is an offtopic.
I got my M51 yesterday and I am not fully sure yet about battery lifetime. I have charged it to 100% and about 8 hours and 2.5 hours secreen time later I am at about 90%.
Coming from my Moto Z Play I am not sure yet if I stay with the galaxy. The Mot Z Play with Incipio OffGrid Wireless Power Pack mod is about the same size and weight. Though provides less capacity (3300mAh phone + 2200mAh power mod) but battery lifetime still was bout 3-4 days usually.
The M51 is also getting considerably warmer during use.
I noticed also the Samsung battery saver with medium settings can reduce the CPU clock to max out at 70% which is handy. Not sure if there is any undervolting, underclocking tools as I think I would be perfectly fine with less performance - actually I was able to reach insane battery life on my old Galaxy P1000 with TricksterMod and custom undervolting back in the days.
I still believe better lifetime with the M51 would be possible bz reducing CPU clock and also with better screen brightness control. I noticed many times already that the M51 screen was too bright for me and having to reduce the slider to "minimum" position or very close to it. Also I noticed that the screen brightness slider is not linear at all. So on the last notch on the left side the screen really starts to dim properly while to the right there isn't much change. Also I like still to use automatic screen brightness adjustments but found the automatic adjustment often moves the brightness too high.
Also a possibility to limit the used screen area (e.g. display black bar on bottom/top) would save energy on the AMOLED screen while still providing more than enough screen space.
EDIT: One-Handed mode sort of provides this feature, but not exactly what I was looking for (like cinema-bars on top and bottom and no prominent "one-handed-mode" title.
I will continue to use the M51 for a couple of charges and decide if I am going to trade it again. The phone itself is performing well, supporting VoLTE WiFi calling but seems to lack carrier aggregation for no apparent reason. I strongly dislike the slippery, fingerprint-attracting, cheap-looking plastic backside of it.
I also hate that everywhere you tap it tries to sign up to a Samsung account. Also replaced the launcher with Nova launcher.
Below is the answer to almost all above useless posts
Battery life tests - GSMArena.com
Why I say useless ?
Simply. SOT will be completely different when you read ebooks compared when you watch movies or browse Internet.
Gsmarena does standarised comparison
I am fan of long life battery phones. I used "king" Lenovo P2 for over 2 years. M51 is better.
I'm at the fourth cycle of charge.. and got 15 hrs so far.. have done a heavy idb debloating
maby it will increase over more charging cycles?
i m getting about 20h sot normal usage
facebook lite, browser , youtube , aliexpress and playing alphalt extreme 30 min
wifi and dark mode on
brightness between 10-40 %
data off
location off
this phone have a very good battery
