The Big Battery Statistics Thread

I have been curious about the battery life across roms, people's typical usage, total battery life times, applications which use the
most power, etc, so I thought it would be informative and semi fun if people posted their stats in this thread.
To try to make this as baseline as possible some standards have to be established.
1. Make sure your battery is properly calibrated.
2. Charge the phone overnight.
3. Start using your phone in the morning and do not charge throughout the day
4. When your battery hits ~5% record your statistics in the template below.
If there are any other useful stats you think I am forgetting, let me know. But for now copy and paste the template below.
Stats:

This has been tried many times before. There is no way to get battery stats when everyone's use pattern is so different:
* What widgets are running?
* Email push or pull? Sync?
* Sync off during off peak hours? What times? What days?
* Signal strength throughout the day? (HUGE HUGE HUGE battery influence) NOT BARS but dbM
* Complete list of programs installed
* Running programs (must be recorded a few times during the day)
* Screen Brightness
* BT (paired, in use, A2DP, etc)
* GPS
* What is "Heavy, medium, light" for text, email, voice, web, movies, music?
Smartphones have gotten so smart that there are to many variables to achieve any useful trending this way. Voice minutes are quatifiable, but that is greatly influenced by signal strength.

suppose you are right. it should be the following:
Battery Life:
GOOD (Y/N):
NOT GOOD (Y/N):
lol

I can't get consistent results at all.
What is the longest time you've ran your phone without charging?
This is mine. Stock JH7 (minimal web, used for email/text/phone over time period only) Battery was at 10%
http://imgur.com/qNlr6.png
3 email accounts. All push
I adjust brightness. It was set all the way down.
NoLED for notifications. 5 minute display window. Only activated when on silent/vibrate. Phone was on silent/vibrate 8 hours for 3 different days.
Less than 10 minutes of GPS testing
Too many programs installed to count (50+)
I was really shooting for 72 hours, but I had an important call in the morning so I had to charge it.

Mine got a lot better after JH7. I can use it all day and have 30-45% when I plug it in before bed. I used to have to be careful and/or plug it in at the office. Beyond that, well, it varies a lot day-to-day.

im about to flash froyo ....hop that makes my bat life better

I get a quarter of a day before I switch batteries.
OTOH on days with no WiFi available, the battery lasts a half day (12 hours).
Battery life is better than the Moto and Nokia I had previously.

TF and dock battery log

Just posted this in another forum, thought it might interest some people here...
Hi all,
With all this talk about the dock loosing its charge and noticing it myself, I started a log on TF usage and battery. Started at 6am yesterday with a full charge in both. The TF stayed docked and turned on the whole time. From 6am to 5pm, the TF was on plane mode (I don't have wifi at work anyways) and the rest of the time wifi was activated. No special program was activated or deactivated. regular programs ran in background (email, splashtop, mynet, maps...) Here is the summary of the log:
6am to 5pm - about 1 hour and a half of use (moving icons and widgets, using catch notes, polaris and took 2 pictures), rest of the time the TF was in sleep mode. All the time in plane mode.
5pm to 10:30pm - Wifi activated, used continuously for 3 hours trying out Springpad, emails, tapatalk, watching a flash movie for 45 min.
10:30pm to 6:30am - Sleep mode with wi-fi activated.
6:30am - light is flashing and TF at 96%.
So, in 24 hours, the TF was:
Sleep + no-wifi = 9.5 hours
Sleep + wifi = 10.5 hours
Use + no-wifi = 1.5 hours
Use + wifi = 3 hours
The dock battery lasted for 24 hours with the TF never being shut down. This is with 4 or 5 hours of use. If we extrapolate, the dock+TF battery could last 48 hours with the TF turned on all the time and 8 to 10 hours of email/navigation use.
This is about 4% discharge per hour. Which I think is a lot since most of it was in sleep mode. Not very impressed with these results. Thoughts?
My feeling is that the dock IS discharging more than it should be. I undocked the TF with 92% of battery charge and will keep logging.
Tell me if you want me to keep posting these kinds of logs.
Joël.

Hourly drain poll & discussion

Let's investigate the hourly battery drain!
To start it, mine after 5 days of usage is close to 3% per hour.

Your results will be varied. You really need a lot of information to compare usage and battery drain.
1. LTE vs no LTE
2. If LTE what is your signal strength (can be negligible or a huge battery drainer)
2. BT state
3. Wifi State
4. Location Setting On/Off
5. AOD state (the number 1 battery drainer)
6. Tilt to wake state
7. Amount of notifications/calls/text
8. Screen Brightness
This is a tough are to analyze unless you have everyone state what their setup is like. You will have people that use minimum settings and report 4 days. The people that use all features and get 1 day will wonder why they are not getting 4 days use. Until you compare similar setups and usage don't get overly concerned with what others are getting.
My setup:
1. Version LTE (T-Mobile)
2. Mobile Network set to Auto (I am in a strong coverage area) ( I leave my phone on my desk and go into stand alone mode several times a day)
3. Call Forwarding On
4. AOD On
5. Tilt to wake Off
6. Location On
7. Wifi Off
8. emails~25, text~15, calls answered on watch~2 (1 minute calls)
With those setting I get 3 - 3.5% battery drain per hour. Full day use 7am - 11pm I put it on the charger with about 50% battery remaining.

Frontier BT version
Aod off
Brightness 2
Dark watchface
Wifi off
Location on
BT always on
~50 messages/d
~10 phone calls/d
1 hour/d playing with new apps and stuff
1 hour/d running or exercising

GS3 Classic BT
1. no LTE
2. N/A
2. BT connected
3. Wifi when BT disconnects (never)
4. Location Setting Off
5. AOD on
6. Tilt to wake state enabled
7. Amount of notifications/calls/text - 30 notifications/hour
8. Screen Brightness - level 3
Close to about 4%/hour with the AOD. I wish we had a way to disable seconds display in AOD because that would probably save some power.
Really kinda roughly the same energy drain of my Moto 360, Huawei watch, and Gear S2. I expected better. Still a sweet watch tho.

1. T-Mobile LTE
2. If LTE is on I use about 10% battery/hr because of crap signal
2. BT auto (primary method of connection)
3. Wifi auto
4. Location On
5. AOD off
6. Tilt to wake on
7. Notifications from phone only if not using the phone
8. Screen Brightness at 8
With that I get about 3 to 4 days of battery life on average (excluding using any LTE).
With LTE enabled I would expect a lot less, where I intended it to be on, at my place of work, it's constantly searching for a signal or has a horrible connection possibly helping to drain the battery. Not sure how it would perform where I have a good signal strength though.
**Edit**
Also, now that I don't use LTE while at work, I use airplane mode and I lose about 1% max every 3 hours.

I get around 3.5 - 4% per hour. But I have EVERYTHING maxed.
non LTE version
max brightness
max volume
AOD
vibration
location on
gps
wifi auto
bluetooth connection to phone
All s health tracking (steps, HR etc)
weather sync every hour
all notifications (email, SMS, Whatsapp, Google, Facebook, Instagram etc)
tilt to wake on

Another observation, at night, lying on the table, it consumed 5% in 11 hours giving 0.45% drain.

My first week with the S3. Came of charge at 7am on Monday and lasted until Saturday 7am. This represent a drain of less than 1% per hour.
AOD and tilt wake-up off
Brightness at 7 with dark watch face
Bluetooth on for notifications and weather
Wi-Fi off
Tracking sleep at night
Not tracking anything else
Location off
Amazing watch. I love the size. I miss the s2 classic impeccable build quality but battery and GPS tracking are too good to skip.
My main issue with the s2 battery was the drain when listening to mp3 on Bluetooth headset. The s3 still drains quickly but not as fast.

From 100% to 84% - 24h so, less than 1%
Non-LTE
AOD off
tilt wake-up on
Brightness at 6 with relatively dark watch face (Alpha Dark)
Bluetooth on for notifications and weather
Wi-Fi off (on if BR disconnect)
Tracking sleep at night
S-health - tracking steps, floors, etc
HR on
Location off
S-Voice off

It consumes about 1% / hour whilst I'm wearing it during sleep, so about double that.

I have to say this watch is totally not consistent with a lot of things. I can live with it for now but for example I walked about 20 floors today (12x3 meter + 5 or 6 times 4 meter at work plus just now 2x4 meter at home) and the stuoid watch counts 3 floors. What a mess. It also keeps insisting I live eiher 18 meters below sealevel or 20 above and hilariously I did a run yesterday showing an elevation of -112 meters.

Just got my S3, so I'm not goin to chime in yet. The first week or two will be brutal for the battery because I'll be in "ooooh new toy" mode. Once my usage settles down to casual, I'll have a good idea of battery life.

Battery Information

My S7 drains like 7 percent from 100% fully charged to 93 or even to 90% sometimes overnight without even touching it. Services running are system sync, email sync every 1 hour, and only system apps running in the background. No Google voice command. Is this normal?
Below screenshot was taken just a min ago. I was watching 720p videos for 3 hours with max screen resolution and brightness set to halfway.

[Tutorial] How to get 14hours of Screen On Time!

I'm in HAVOC 2.0 OFFICIAL (Pie), but it will work with ANY custom rom. If you don't have the 1st option Smart Pixels in "Havoc Settings" ('cause you're using another Custom Rom) you can use the app: "Pixoff: Battery Saver" or similar...
Tutorial>>>>>
1 - Havoc Settings > Screen > Turn on Smart Pixels (62% of pixels disabled), and increase the brightness just a little to compensate.
2 - Use Greenify along with Greenify4Magisk module to freeze all GCM apps.. But you can just disable GCM and other stuff in "MyAndroidTools Pro" by yourself decreasing the need of freezing unnecessary apps... but you have to understand how android works or you will break your system (USE WITH CAUTION). (A 1 million dollar tip here: Disable things like "analytics", "gms", "GCM" (if you're not finding those words tick this icon "<-->" to expand the service names..
P.S.: Only play with Third Party apps... Don't mess with system apps!
3 - Use Naptime to make Doze mode work properly...
4 - Use AfWall+ to block all apps that don't use internet to leak data and hog your battery unnecessarily.
Extra Magisk modules I'm using:
- AdGuardDNS Adblocker (unofficial)
- Sysconfig Patcher (sp) helps to doze Google Play Services and system apps that hogs battery...
- Swap Torpedo -> to SPEED memory.. my old devices 1gb ram runs blazing fast with this and it works so f**cking good in Note 5 aswell..
* You can turn all animations off systemwide and your experience will be better IMHO
You can tell me if it worked or not.. But I'm getting 14hours of SCREEN ON TIME. :victory::laugh:
In the screenshot below I was in 7h39mins of Screen On Time with 50%... I'm just sharing all these stuff 'cause I finally manage to have a GREAT battery life. I used to mess with Amplify app once and didn't have so good experiences (Phone app missing calls and whatsapp doesn't showing notifications), but maybe someone else manage to get a better SOT than mine, using it properly..

Nice share
But usually the SOT is not the similar that you would get from 100 to 50 % battery and from 50 to 0 % battery. So it's not fair to say the SOT would double by sharing a screenshot of 100 to 50 % of usage.

If my usage will keep the same (4G always on: Whatsapp + Opera (facebook site mainly) + Instagram + editing photos on Snapseed + gallery), my estimated SOT is 12-14 hours.. I will post a new 100% test screenshot to prove you.
I mean, if the mAh consumption will keep the same over the same kind of usage, it's easy to trace a statistic number over it. Ok ok.. You want proof, just test it and tell me.. I had to plug the phone in PC to install some last apks.. But tonight was my final installs and tomorrow I will test it from 100% to almost 0%

Getting 11 hours of SOT on Revolution OS & Insigniux kernel and no tweaks at all. My usage consists of a lot of YouTube, reading books on the Kindle app, playing some games, and the usual social media (whatsapp, twitter, instagram). I also listen to a lot of music via bluetooth headset (about 5 hours per day). The phone lasts almost 2 days with such a usage. So yeah, I think this is more than enough for the average user such as myself, no need for all the hassle you posted above. It's really unnecessary.At this point, this is just turning to a "who has the best SOT" battle. Even 7/8 hours of SOT is something great for this device, while 800/1000$ flagships are struggling to push over 5 hours of SOT.

Thanks a lot for the time spent writing this. Would you have more information about the firmware and kernel you're using ?

First, to everyone that read OP, realize there are some inaccuracies. Sorry man.
Smart pixel settings and apps like PixOff only save battery for OLED displays. HAVOK OS is available for multiple devices and this feature is beneficial for devices with OLED displays, but does not make a difference to LCDs.
Our phone has an LCD display which cannot actually "turn off" a pixel . It consumes the same amount of battery no matter what color it displays. Display brightness makes the biggest difference in display battery consumption.
So by turning on "smart pixel" and increasing the brightness you are actually HURTING your battery life overall.
Secondly, you only tested from 100-50%. You will ALWAYS get vastly more battery life from the top 50% than the bottom, because batteries voltage does not drop linearly, it is chemical reaction that is actually quite hard to measure accurately.
There have been many times where I was "getting 14-15 hours SOT" in the top half, but then watch as your battery drops from 40-20 from only 1 hour of light use. I can almost promise you this guy won't actually get more than 11 hours by the time he hits 0.
Use it from 100-0 at least 10 times , showing 13-14 hours of SOT and I will actually believe you are on to something.

On MiUI 9.5.17.0 I already can achieve close to 14 hours SOT, but that is within 1 day 10 hours usage. Usually I get 11-13 hours only within 1+ day usage. On AOSP, specificly RR 6.2.0, I easily reach 4-5 hours SOT by 70% (which I usually charge it already), 15 hours if interpolated to 2 days usage. 10 hours SOT is almost guaranteed. Last test is 13 hours SOT within 2 days 2 hours. If you want to see what is the configuration and usage, just check the link. I prefer to state my configuration and usage during the test, to show any possible different variable.
1. SmartPixel AFAIK is useless in IPS LCD. I would prefer the full maximum resolution as not to downgrade my user experience
2. I don't use any greenify, simply use the battery optimization from android. I whitelist several apps : Automagic, GMD gesture, Whatsapp, MiXplorer. I never clean my recent/RAM. I remove the "nuke button" from the configuration.
4. I don't know starting from which version, but since Nougat 7.0+, we have the setting to restrict data usage for each app in the app info. I simply create a flow to automagically open the app info everytime I install new app and decide whether to restrict the internet usage or not.
For ads, I just use hosts based - adaway. I don't limit play services, just let it run normally. I don't tweak much on the RAM side, but I adjust the minfree on every reboot (using automagic) to the lower value than default by RR. This is to let more apps stay on RAM as long as possible.
I don't want to limit the phone's perfomance to ridiculous level. Smartphone are meant to be used. The battery used is the proof we enjoy technology. Of course if the drain is unusual and wasted, we have to troubleshoot and find the culprit, as I have done in the wifi deep sleep drain bug. But other than those exception, I want the full user experience I can get from my phone.
SOT Variation
SOT is kinda non standard way to measure the usage. It varies depends on the user habit and usage behaviour. I am using dual SIM with good signal in most of the time, no microsd. Common usage :
- idle with no internet : 0,3-0,4%/hour
- idle with wifi : 0,5%/hour
- idle with LTE : 0,6-0,7%/hour
- Screen on dim (brightness < 10%) : 5%/hour (outside of idle drain)
- screen on bright (brighntess > 80%) : 10%/hour (outside of idle drain)
- Play game : Depends on game, it can consume 8-20%/hour
Using basic math, If 25% are used for the idle with wifi, I can get 25% / 0,5%/hour = 50 hours usage. 75% for screen dimmed, I can get 75% / 5%/hour = 15 hours. So 15 hours SOT is possible within 2 days usage. This interpolate nicely with my 70% 4-5 hours SOT.
But If I use the phone outdoor and the brightness increase, I can only get half of that, 7,5 hours SOT only within the same 2 days. Or maybe 9 hours SOT within 20 hours usage. If I have bad signal, it will reduce even further, 5-6 hours SOT only. Playing heavy game (PUBG) usually reduce the SOT by half too. So playing PUBG in dimmed brightness will consume 10%/hour and in brighter, 20%/hour. Increasing/decreasing the graphic also modify the drain per hour. Usually playing heavy game result in max 5-7 hours SOT only. But sometimes I can still get projected SOT around 10 hours, depends on what game I play and how many hours I played it.
Taking it to the extreme, we can spare 10% for the wifi idle, giving 20 hours usage and 90% for screen, giving 18 hours SOT. Which mean we can achieve 18 hours SOT within 20 hours usage. I am quite addicted to the phone. I use it for browsing, learning language, reading ebook, watching video, designing flow in automagic, usually without any gaming. But even then, it is very difficult to use the phone straight for 18 hours within those 20 hours (without gaming).
It is very difficult for me in usual daily activity to test the battery life till 1%. I usually have to plugged the phone for screen mirroring or transfer data. It will skew the battery usage then. I also usually just charge the phone at around 60-70, sometimes higher, sometimes lower.
At this kind of battery life and perfomance (SD636), I am very happy with current usage without the need to tweak so much again. Just use your phone as usual and only troubleshoot the battery life if something drain too much without doing anything useful. Enjoy your smartphone.
