[v1.2] Getting better battery life from your Motorola Milestone

I have just completed writing article on how to improve your battery usage with your Milestone.
http://bit.ly/milestonebattery (google doc, no sign-in required to read it)
Article includes the results and data gathered from a form many of Milestone owners used to submit their own information. The form can still be accessed here.
You can still ask any question regarding battery problems you're having. We will gladly help you out
History:
v1.2
* finished writing document. still updating it.
v1.1
* created google form and added suggested fields (ty 400757 and hefonthefjords)
Thank you everyone who participated (and still is participating) in this project!

MOD name & version: Cyanogen beta 0.04-10.11.16
Manually overclocked (Yes/No/Freq/Vsel): 900-58 700-48 550-42 250-28
My Location (Settings): Both disabled
Manually build.prop edit (If Yes, please explain what you did): WiFi Scan Interval 60
Wifi usage (include sleep policy, if any): disabled, turn on manually when downloading apps
Data usage: enabled
Sync usage: enabled
Data network used (2G/3G): 3G, 2G when screen off
Power efficiency programs installed (Task Managers, Battery Managers): SetCPU, Watchdog Lite
Informative widgets installed (Battery Status, Weather info, Social,...): Beautiful Widgets (weather and time, 2h update), Watchdog Lite, Watchdog 3G, Pure Grid Calendar, LauncherPro Calendar (Agenda)
Number of processes running (Settings>Applications>Running Services): 10: Titanium, Pure Grid Calendar, 3G Watchdog, Tasker, Kik, Vlingo, KeepScreen, SetCPU, Google Messaging Service, Swype
SMS/MMS messages per day: 5-10
Calls (in minutes) per day: 0
Data transfer (browsing, chatting, using social apps) in minutes: ~200-250
BATTERY TIME PER CHARGE: ~10 hours
Notes: Days where I boot into recovery and apply updates/nandroid backup, the battery is much worse. I should probably remove keepscreen and vlingo because id otn really used them. Brightness is set to dim. manually increased, using cyanogen notification bar power widgets, if needed (which isnt very often). music playing for about 2 hours a day as well

Seems to be better to put it on Google form?
Both easier to input and sort out and draw a chart.
What is the objective of the survey? Are you trying to perform data mining on the survey result to derive which pattern is more battery friendly or badly?
I think the battery usage statistics should be included as well? (both the % and time)

You're right on that. I'll try to make a survey with stats at the end. And yes, i'm data mining or struggling to find the cause or more of them, to see, which part of the phone is also the reason of huge battery problem we're having. Its not that we have a million more choices... some also reported bad battery life on 2.1 but i'm not sure this is software related then.. give me a day or so to make it happen then

Quoting again- just created form. Please help out if you can

Form submitted..

good call on setting this up.
form submitted.
you should probably add the question "battery percentage remaining?" after the time since unplugged bit so that we have a more accurate idea of how much use people are actually getting from one full charge.

Updated. Keep them coming. Mixed info at the moment. Remember, its the data we need, the more data, the more accurate informations.

I want to say something about battery draining of my milestone.
I recharge it until morning then go to work.At 12AM the battery is at 15%.Hmmm.. so i did some research..i updated to Cronos 1.5 ROM and then i did something unuasual.
I rebooted the phone when the battery was at 15% level. When it restarted the battery had 80% power and it lasted till night. Do you have any explanation?

Hm, maybe there's something about it we have in common.
I usually went to bed with 80% of battery. When I wake up, its at 30%. Now, if I start charging it, the battery charging indicator shows as if it would charge it from 80% to 100%.

thank you! This dodged me till now. Had the same experience with battery as some of the guys here.

Okey done!

Hi all,
Form was submitted 22 times until now. There are some amazing stats included with some, that suffered the same problem as I did.
okorn is the winner at the moment, with 15% to go, his phone lasting 40+ hours on Telus Lite (Eclair!), where the longest on Froyo would be more than that (petyo.tsanov) running Cyanogen Mod for 20hours and still having 60% of his battery.
Its too early for any conclusions, but,.. just for info, most of us/you who filled the form did have some kind of sleep policy on (data/2g-3g-wifi).
I'll try to show you all results by the end of the week with all info
ps: Its still not too late to submit your info about Battery drainage at http://bit.ly/motodrain
Thank you!

Form sent.. have a good work!!
=)

GPS test
hiya ! ..
i did a GPS test on a hike last saturday ... with offline maps and oruxmaps set to
record position every 2 minutes ... phone was in flight mode, killed all apps on
startup.
at the end of my hike (approx 10.5 hours), the battery was at 60% and 3818 mV
with time since boot - 10 hours 49 minutes.
this was on stock 2.1-update1 ... i'll be doing a similar hike this weekend ... will
use the G.O.T leak + cyanogen mod beta 0.04-10.11.20 ... shall post results
once done !
cheers !

perfect test! do post results!

Hi all. I just finished with my project about battery draining. I've made an article about it, including results.
Check it at- http://bit.ly/milestonebattery (google doc, no sign in required)

Speechless.. you did an optimum work!!!
Hoping it will improve my MIlestone life!!!
Another thing I tried today: I tried to FULLY discharge the battery, and then charging again.
Turned on in the morning from a full charge, my MS fastly went to 50% for lunch time, after middle usage. Then, at 30% this afternoon, I decided to discharge it viewing YouTube with maximum luminosity on display.
After few minutes, 20%, then 15%, 10 and 5. In short words, it decreased from 30 to 5 in 12 minutes.
And then, the surprise: the Stone played YouTube video in WiFi streaming for over 40 minutes, staying at 5% and red led blinking continuosly! So I ask, maybe a big problem of Milestone battery life is just an incorrect reading of the battery level?
Can you try, just to see if it is my only case, or it is a common case?
and thanks again for your work!!!

anyone have bad battery life?

i see that a lot of people are posting amazing battery life results.. but no matter how hard I try, mine simply doesn't last 3 days with 8 hours screen on time etcetc
things ive tried:
factory reset then just install the essentials i.e. facebook, whatsapp, zite, mxplayer, pocket, myphoneexplorer.
battery calibration i.e. drain till dead/cant switch on, charge from 0 to 100 with phone off
adjust wifi, gps, autosync settings
and yet, see my attached battery stats. and that's with relatively light use (sat on my office desk) @ 2hr screen on time. no gaming, the most taxing activity was probably watching a movie with mxplayer for 20-30mins or so. the phone died completely 3 hours later.
my firmware is 81.5.39001.xt890.Retail.en.GB
it would SEEM that the battery goes down real fast with any usage.
i want to love the phone but it's not letting me.
thoughts?
firmware versions and screenshots of bad battery life please? lol

Well, mine does not last as well as advertised by others but likely better than this. It can get up to 5h of screen on time in web/video usage and maybe 3 days with less than 1h of screen on time. It also dies very quickly after 10%, 7%-4%-0% shutdown. Germany EU Retail stock firmware. Not the best battery i guess

Well my battery usually last between 1d 3 hours and 1d 20hours with usually display time between 1h 50m - 2h 30m and talk time 45m - 1h 20m talk time, with data or wi-fi always on , autobrightness always on and auto synch always on.
Facebook app and Whatsapp are mainly the guilty apps for the power consumption and data usage .... Without Facebook and Whatsapp installed and with ONLY wi-fi data i had superb power consumption .... 2d 10h and 4h 55m display time with 1h 30m talk time.
PS 2 more things that comsume power in Razr I are 1) music player and 2) FM radio

thank you for the input guys
@kourkoubas, i think ours is similar then
but i've yet to try turning off facebook autorefresh. sadly whatsapp must stay
i use Music/Pocketcasts everyday but then it's no more than 1 hour combined.
i think ill have to do more testing. that other battery stats thread got my hopes up too high i guess lol
@Simplestas does your screen brightness flash wildly just before it shuts down?

I was a bit disappointed with my battery, too. I read about those 8hrs screen on time and was just stunned. It depends a bit, how i use it .. Usually i have WiFi activated almost all day in university and at home / girlfriend. With 2.5hrs screen on time i always have ~50-60% battery left. Thats a common value for me as i sometimes need my phone for .pdf viewing. I normally have the brightness reduced to ~15%.
For me, it was a huge improvement over my old Desire HD, but it still could be better. Anyway i don't want to forget the fact that i used JuiceDefender with my DHD and used every option i have to improve battery life while i just don't have to at my razr i, it just doesn't die one evening or in the middle of the day like my DHD used to.

@Simplestas does your screen brightness flash wildly just before it shuts down?
I don't think so.
Try testing if taking pictures with flash works with battery < 50%. If it causes immediate shutdown your battery is likely faulty.

The Battery life was on the beginning really good but now its getting worser

well the battery % seems to be correct.. have attempted to calibrate it quite a number of times now.
it's just that the screen backlight becomes er.. like a flashlight running out of battery- dimming and returning to normal brightness a few times just before it shutsdown at around 2% battery level. just wondered if this is a common behaviour with xt890s/medfield cpus.
because ive never seen this in other moto phones nor any other smartphones for that matter.

well i believe that somebody out there is having really good battery life... just not everyone, sadly.
other than the outrageous 8hr screen on times etc, there are quite a few review sites praising its battery life so we must be missing something and i want to see if it's possible to find out what.
i agree though juicedefender work wonders.
used to rely on it a lot. now I just occasionally use "autosync free". it's more than good enough.
but i don't want to rely on these methods yet..

define good
let's see some stats
and what firmware are you running?
"worse" could just be the new apps you're adding to the phone?
cheers.

6h of screen time already IS GOOD, very good.
4h is what what sgs3 usually gets, 3h is what the n4 gets so 2more hours aint good? Everything gets +-2h with different usage e.g. google now and being on the move, mobile data...
It all depends on your usage but its about 25-50%better then the other quick phones around so please stop *****ing because u saw some very good screen and now cry because all your widgets, push email, chatting, mp3 destroy the screen on time you get
@yellowchilli: sry i cant see your attached screenshot, forum doesnt let me but if you usually get 2h of screen time you should call the support and get a new phone because thats not right.
edit:now i can see it. What did u do with the phone except watching a movie ? Nearly 3h aint critical i cant tell if thats normal or not it could be that you listened mp3 ... if you bought at a store go to them and get a new one anyway the store i bought in wouldnt mind changing it so i hope yours does the same

I get about 2-3 days with minimum usage (auto brightness, WhatsApp, Twitter, occasionally a phone call or web search or camera shot). I have the latest GB retail firmware, no root or whatsoever. Completely stock ROM.

Mine also never got past the 3h30 screen-on time, even if I didn't use it for much else... should I take it to the nearest customer support site?
Also, the phone gets real hot when the screen is on for some time...

This is what I get usually and I love my battery...
Running stock rom 39001.retail.en.GB
Non rooted

Battery life?

Hi guys, I have a question about the xperia zr, how is the battery? gsmarena posted some impressive results, but how about in real life, can if get 5-6 hours of screen-on time? my gt-i8730 can do 6 hours normally, how does this act? thanks )

Yes.. for me it lasts for a long time screen on
you may check my review on the 4.3 FW
• Battery Life Test •
------------------
-These tests depends on my own usage ,so it may differ depends on everyone's usage-
• Average Usage •
it lasts for 1 Day and 13 Hours with average usage
~4:30 Hrs Talk Time
~23 Hrs Wi-Fi On
~3 Hrs Screen On (Chatting ,Browsing and downloading)
• Heavy Usage •
it lasts for 10 Hours with continuous heavy usage on medium brightness with the auto enabled
~5 Hrs Screen On (Chatting and Browsing)
~8 Hrs Wi-Fi On (using it even when the screen is off)
~2 Hrs Talk Time

Yes it's very impressive!! Let's say, you can reach evening without any problems even with medium/heavy usage. With "medium/heavy" I mean if you turn on GPS for 20 minutes navigating, 24 hours of wifi/data switched on, 1 hour of browsing, and texting all the day. But the very impressive thing for me is that if you play 1 full hour with a heavy game such as riptide, the battery doesn't fall down, you will lose only a 6-8% of battery. I tested the battery with cyanogenmod 11 and stock 4.3, well, the stock firmware battery usage is better by far!!

I'm pretty sure you're guaranteed at least 6-7+ hours of general on-screen usage, assuming you don't have a thousand things forcing every CPU core to be at max load.
I bought the phone having read the gsmarena battery benchmark results for it, and I can say from experience that they don't come close (as in, worse). Same for the standby time on the phone is not what is stated by Sony/GSM but of course it's still a pretty amazing phone, for me I bought it for the supposed crazy good battery life (11:20 hours constant web browsing? I get half that) which isn't an improvement from my old phone so probably going to sell it.

gaming will drain the battery more quickly, but that's the normal for every device
but for internet usage it lasts with me for 10 Hours
~5 Hrs Screen On (Chatting and Browsing)
~8 Hrs WiFi On (using it even when the screen is off, downloading, VOIP..etc)
~2 Hrs Talk Time

I searched for your problem, here what i get :
The media server application indexes all your media on the phone.
Its common that if you transfer media files to your phone that the power consumption of the media server will go up but only for a short period of time. This is necessary, otherwise app's won't be able to find your newly imported media.
But in your case, since you seem to be having troubles with the media server app constantly consuming battery. I think that you may have a/or several corrupt media files in the phone or on your SD card. Causing the media server app to constantly trying to index files.
Just to do a quick test, try to copy all your important media and other files to your computer then delete them from your phone or do a format on your storage memories and check if you still experience this.
If you don't, the problem is as I suspected a broken or corrupt media file. The hard part is to figure out which one.
Source
And while searching i found some app that might fix your problem (it requires Root permission) , it's called Mediaserver Killer, get it on Google Play Store
i didn't test it but there is some positive feedbacks about it

Mediaserver is an apps running in background. So Check which apps you installed recently. Uninstall then.
Normally Utter, proximity sensor on/off, open mic+,. Wifi GPS seeking apps, This are just example. Find out.
I had same problem two month before. I don't remember exactly which app was causing problem but I unstalled some of them and got result.

Open your walkman app, and then on the right top, when you click that you see mediaserver there.

lowering quality and turning off aod/edge lightning will only save you a few minutes, you may as well have them on enjoy the features.
The SoT is user dependant, everyone uses there phone for different things and in different ways.
Also your phone has been on for over 20 hours, im sure you would get the same SoT as the rest if your phone was not sitting (screen off) running apps in the background for so long.
Having said that spotify is one of the things you have used in that 20 hours and judging by the %4 it used i'd say you were streaming a fair bit, that obviously does not add to your SoT but your still draining the battery. if you use your phone mostly idle while streaming music why does SoT matter?
No one can "help" you here i don't think, it is your usage habbits, this is what you get im afraid and from what i can see its not bad at all
my only tip would be if you dont use your phone turn it off instead of letting stuff like facebook eat away at your battery all day for when you actually do want to use it for Netflix or whatever :good:
Edit: Also your only at %25 still can get a couple hour SoT out of that :silly:

Having said that spotify is one of the things you have used in that 20 hours and judging by the %4 it used i'd say you were streaming a fair bit, that obviously does not add to your SoT but your still draining the battery. if you use your phone mostly idle while streaming music why does SoT matter?
No one can "help" you here i don't think, it is your usage habbits, this is what you get im afraid and from what i can see its not bad at all
my only tip would be if you dont use your phone turn it off instead of letting stuff like facebook eat away at your battery all day for when you actually do want to use it for Netflix or whatever :good:
Edit: Also your only at %25 still can get a couple hour SoT out of that :silly:

I started netflix after taking these Screenshots , Atm i m on 11% and my sot is 3 hours and 13 mins . 14% batt gave me 1 hour + sot which is decent right ? Something just sucks so much battery when the phone is on idle

That's normal, that's how you receive instant updates from emails WhatsApp etc Facebook is an idle killer. You can either put the apps to sleep so there not active while idle or turn the phone off all together when you don't need it. Like I said I don't think there's anything wrong with your phone it's normal not for me but it's normal for you.

Samsung has one built in.
Go to Settings > Device Maintenance > Battery
click 'Save Power' that will put your apps to sleep.
Also you can scroll to the bottom of that page and press 'Always Sleeping Apps'
and you can add what apps you want to that list and they will never run in the background while the phone is asleep.
Alternatively you could use an app like Greenify.

You can try "greenify" at playstore, it is free, and a donation pkg that further enhaces its features

Question Battery life not as expected

So i got my S21 Ultra a couple of weeks ago and the battery life isn't as good as people tell it to be... I wonder if this is normal or i have a faulty unit
Important: i am running the latest update on my exynos device (february security patch as of the making of this thread)

What do you expect? You have used the phone almost 12 hours, used Samsung Music for nearly 8 hours and still have 78% battery left lol. This is great.

The SoT is pretty crap i can only get 5 to 6 hours if i'm lucky, all i do is watch youtube and netflix and nothing else pretty much, and since SoT is pretty important to me idk if i should wait for an update or get another unit

If you are comparing to a Chinese phone, I would agree that the battery life is not great. Before buying S21 Ultra(exynos), I was using Mi 10T pro. It has better battery performance than S21 Ultra. The other thing that I dislike about would be the heat issue on S21 Ultra. Its horrible.

SOT is only one measure of battery life, the battery still depletes when the screen is off, especially if you're doing something like listening to music for 7 hours......
If you saw the YouTube 'battery drain' tests, the majority are in a room, mobile turned off and on WIFI. They are in constant use with minimal ramping/up down of the processor as they only switch apps every hour. These guys achieve up to 9 hours with constant use in optimal conditions.
If you extrapolate out your current usage you're on for 7 hours with 51 hours total, which is very very strong. People would kill for that endurance
At best you can expect 0.5% an hour drain if you aren't using the phone, but that's if you literally leave it overnight and don't touch it. More likely it'll be between 1-2% depending on usage, so if you calculate you've had roughly 10 hours of screen off, that's about 10% battery that isn't being used on screen on time, which equates to roughly an hour of SOT 'missed out on' if you were just to run the device with the screen on for the sake of it.
If you're truly only concerned about SOT, run a day without music in the background and see the improvement. It's a nonsensical thing to do as that's not how you use your phone, but will get you the numbers you want...
You're also using a high end processor and a large screen with a high refresh rate, it's going to use more juice than a mid range or low end phone. If you send that phone back, someone else is going to be very happy when they get it as their replacement

With my s21 ultta i can easily achieve 10-12hours of sot with browsjng and youtube on wlan with total runtime of 48hours.on mobile data its a good 35% less (also cause of brighter screen outdoors) but Overall its good battery life for me (note im debloated and using Samsung browser with darkmode!!)

I'm doing OK on the battery. Turned off goggle discover on side screen has helped aswell as 5g disabled as I don't have it where I live atm

Yea it'll be the 60hz getting you through then, makes sense

Yes if you want the same smoothness and a good 10% better battery you can use the 96hz mod

Put brightness on manual. The display eats a lot of the battery. Try to keep it at 50% or less.
Turn off all animations and use dark mode/dark wallpapers. Junk like tic-tok, fb don't help.

Fb is malware, I don't care who or what's on it, it's off limits. Instagram... no way.
Tweeter just as bad as fb. Full boycott on all that junk until they f-f-fade away
Been using manual brightness control for over a year on my 10+. Occasionally I toggle it on but rarely. Going full brightness will greatly reduce OLEDs finite lifespan. Blue goes first... and the burnout isn't even. If I can get 5 years with just a battery change or two, I want it.
So far between Samsung's and Android's weak offerings I have zero incentive to upgrade hardware or firmware

Yes but if you are using them in tge browser they cant suck your battery up and im only using them for roughly 10minutes a day so no problem. But youre right they are like malware... Traking your location every few minutes and that ****

I do 20-30% charges throughout the day.
Crap like Twitter and fb can cost you your job as well as privacy leading you open to attacks of all kinds. Zero rewards and lots of risk. No.
Remember the night of the long knives?
Think how much easier it be to do now...

Has there been testing on the battery effect of different wireless network modes, including while being connected to Wi-Fi?
I understand that 5G uses more battery, but I'm curious how that is affected when you remain connected to Wi-Fi for all data transfers (using 5G just for calls and texts).
Same question for the other network modes, like LTE/3G/2G vs LTE/2G etc. Or also when you are not connected to Wi-Fi.
I can't help worry that some people are getting bad battery life because they have a poor network signal?

Only rough but very little difference between 4g and WiFi when still, and that's in a location with 2 bars signal. Seems like the phone sleeps better with mobile data on.
It's hard to make a direct comparison with WiFi Vs network, as a lot of the network drain is when moving and polling for new antenna. When looking at signal strength, 4g/5g have the same dBm and 3g/2g have the same dBm, but 4g needs less dBm for a higher transfer rate than 3g, so may use less power over time.
Also I don't think 5g is inherently more power hungry than 4g (I may be wrong), again it's just less available and shorter radio waves, and until now 5g has relied on external modems.

Exactly, I wonder if our S21 Ultra is much better with battery life on 5G, because our SoC includes the 5G modem and it's not external?
My desire is to just keep my phone on 5G while I'm at home idle and the phone is connected to home Wi-Fi. I wonder if there is a battery savings to be had if I switch to LTE while I'm at home on Wi-Fi and the phone is just idle.
