battery life

Just thought I'd give a quick review of Cyanogen Mod 7 battery life and performance.
Standby battery drain of about 1.5%/hr with 3G, backround data on, auto-sync on, wifi on, GPS on.
I've never obtained such great battery life on any stock rom or stock-modified rom (I've tried a few different ones over the last year or so)
The performance is also much better than any of the stock-based roms (no lags).

No need to create new topic for that information.

fan/zombie boys everywhere
aple has ones so why not android ;]

Which nightly are you using? Which kernel?

After a night my Galaxy S is always dead. I solved the problem disabling 3g connection and sync. Stock rom 2.3.3 and semaphore kernel.

Sorry to say but useless thread. Just keep the damn charger always near you and battery life wont matter.
Btw did cyanogen pay you for posting this?or........

haha I had the same thought

I used to always hear about CM7 having god-awful battery life. I don't know if people were lying or if they fixed some major bugs, but I certainly have no complaints about my phone's battery life (running CM7, of course). I get through way more than a day.

That's my current battery stats. Haven't used the phone too much the last little while, but getting over 24 hours is not uncommon—I actually very rarely see my phone last for under 24 hours, and that's usually because of 5+ hours of screen on time. For that battery, I'd say about 75 texts, 30 minutes of phone calls, and about 30-60 minutes of web browsing. Fairly light use, but nevertheless, the battery life on CM7 is nothing to complain about.
EDIT: Looks like something was causing a wakelock the last ~6-8 hours while I was asleep, causing my phone not to deep sleep. If that hadn't of happened, it would still have quite a bit more battery (when I went to bed it was 44%, so it shouldn't have dropped to 27%—it should have dropped to ~40%). This just proves my point even more: battery life on CM7 is not bad at all.

seriusly?
do you see any battery change in that period compared to one earlier ))
when it was awake on your funny screenshot it was discharging with the same when the phone was not awake acordding to that stats so no impact registered

Thanks to share that information...

Best battery life that I've seen, using cm7.1 stable.
Currently at 2 days 1hr 15 mins with 14% remaining.
Wipes the floor with friends phones on stock roms charging every night. I only switched toCM7 after darkyrom barely lasting 12 hours at times

This sounds fantastic, Cm7.1 is my next choice, on XXJVT battery life is only 12h

thats using juicedefender to activate the data connection when screen turns on, emails still push to phone straight away with gmail so it is fine for me.
WIFI seems to drain the battery a bit quicker but not enough for me to bother flashing different kernels

I saw someone who did 2 WEEKS without charging. Normal using with black wallpaper on 2g network.

seems to be even better on ics... the best i had was ~2% per 8 hours...

3G + WiFi + email max 1 day

[COMPARISON] Post your battery life + SOT of your current ROM

Hi, I've created this thread to compare battery life between different ROMS
Post your current ROM, and your battery life ( with screen if you want )
Don't forget the poll !

S4 is a great phone but battery wise it's completely ****ty. The maximum SoT I can get is on stock TouchWiz based ROMs and that's only 3 hours.

I've seen many people with +5h SOT, maybe some useful kernel tweaks, but even with custom kernels I can't get over 2h30-3h

What? Are you sure people can get 5h+? I really doubt that man. They're probably using extended batteries or battery cases.

Yea I don't remember where I've seen it, but they got +24h with around 7-8h of SOT without charging the phone or using battery cases
I could get 50h+ battery life with 10h SOT on my LG Spirit thanks to some tweaking of Interactive governor, so I think it's possible

For me, I got 3.5-4h SoT with my mobile data turned on, both GearCM and stock-based. I'm using a Hippo 3200 mAh battery.
5h+ SoT? Possible. Don't use any mobile data, only Wi-Fi. That's it.
Sent from my GT-I9500

Got 6h30 SOT yesterday and still 40% with Lollirom and Impermium 3.4 kernel, Yankactive kernel
I watched 2 movies, I think Wi-Fi is the major battery drainer

Wow this is excellent !
But I can't live without Lollipop and Xposed

I have a battery issue : my battery drains fast from 100% to 80-75% and then it drain normally
Do you have this problem too ?
I think I'm gonna buy a 3000mah battery

I just bought powerbank, the battery of s4 is worst ever seen. ??

We should get better battery life with 2600mah, maybe a bad battery management ?

My battery drain 100-90% quickly....then it is normal.Give a Try "Repair battery life" app to fix that.
I have galaxy s4 i9505,i9500 i also had nexus 5 and xperia z1 but compared to them s4 battery life is best....i have tasted all phone with different rom and with different trick.......with nexus 5 i can get maximum 5hour sot...with z1 got maximum 4-6 hour sot.But with s4 i got 6.30 hour sot and 1% standby time per 5 hour.....whre nexus 5 and xpria z had 1-2% standby drain per hour.....
Now on my i9505 i alawys got 6h-6.40h SOT even on wifi with "kushan rom 8.0" so try this rom before changing battery.

I've already tested Kushan Rom, but battery was draining fast too
Today I installed GoldenEye Rom with OC/UC Hulk Kernel, PegasusQ governor and some undervolting : SOT is just perfect and standby AWESOME !

run the battery down to nothing, until it turns the phone off. then boot and charge it to full without using it.
if you want to go further, when it's reached 100% turn it off and charge again until it shows 100% then reboot and do the same again but leave it for 15 minutes still charging at full.
always remove the cable when turning the phone off or on !!

use synapse app and under clock your CPU to 1200 MHz and see the result

As I can see, no one can get a full day with Lollipop
Some KitKat users here who can last a day ?

I had it with Optimized CM 12.1

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the OnePlus 7 Pro's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

No one has mentioned it yet so I thought I left a comment.
Standby drain is great. Less than 1.0%/hr in my use case. (AccuBattery: 103h)
Have had Samsung Exynos phones before which had extremely bad standby drain, the Xiaomis I have/had have a lot better standby drain but not as good as my OP7 Pro

I'm seeing between .3% and .8% drain when idle. I think it depends on if I'm listening to music or YouTube vids with the screen off or it's just truly idle doing nothing.

Yesterday I left my phone with 85% over night, nearly all connections turned on (Wifi, GPS, Bluetooth, NFC) and 6 hours later I was down to 82%. Didn't expect that. I love it!

Over all stand by time isn't to bad, but usage of the phone isn't very yet. I've only had the phone for two days and I'm noticing heavier battery drain then from my note 9 the 845 processor. Going to give a few more days and see. All in all I like the phone. Just my thoughts
Sent from my GM1915 using Tapatalk

Well, the standby is pretty nice, according to me it drops like 2-3% overnight leaving Wi-Fi, Bluetooth on. I previously had a OnePlus One, running POSP (4-6 hr SOT) so it feels great upgrading.

It's about 0.5% per-hr for me overnight and 1% during day. Much better than my last phone with far less spec but has a ton of bloatware.
I read a lot of complaints about battery drain in OnePlus' Chinese forum but I think it's all due to unscrupulous apps by companies like Tencent and Baidu who continuously track and steal user info because I also have HydrogenOS but thanks to Oneplus I was able to completely uninstall all those apps.

I have to say standby drain is great. Coming from pixel 3 on busy work days, I barely used my phone outside of phone calls and Waze to and from work. I would get home always under 50% and be dead by 10pm. It's currently 1am and I am still at 44% on op7 pro.

Standy drain is good. It's dropping few percents over night but it's not like 1% or more per hour. More like a 0.5%/h. Even during the day with 4g data enabled its really ok. I'm very pleased with it, definitely better than my old Galaxy S6 Edge Plus which was more and more inconsistent with new updates

do you have ram boost enabled? are you on AA or BA?

Mine drops on average 1.7% per hour according to AccuBattery. I do a lot of YouTube streaming with the screen of though.

Hi,
I have had the OP7Pro for over 3 days now and I think the battery has settled after the initial indexing and setup. The phone was kept overnight at 52% at 10:30 pm and today morning at 6 a.m. it was down to 36% which about 16% drain over 7.5 hours. I don't have a lot of apps running in the background except for Gmail, Whatsapp, weather and normal google services. Is it normal to see such a drain? Or, do I need to need to wait for another 3 or 4 charge cycles for the battery/ system to really settle down?
Amit

Pretty good idle about 0.3 per hr

As always on this kind of threads I see wonder numbers.
I get 0.7%/hr which isn't bad at all, but it's far from 0.3. I am on EX kernel, no other tweaks.

around 2-3% an hour on standby. Got the usual apps (snapchat, instagram etc, no Facebook tho)

My device has abt 5% drop over night but that's cause of Instagram and WhatsApp notifications running in the background, otherwise it's standby time is grt
Battery life also depends upon the cellular signal in your area
Lower signal mean more battery sucking

The most I have seen mine drop overnight is 5-6%, with Bluetooth on an Wireless off. I have had the T-Mobile OnePlus 7 Pro for about a month now and have messed with settings and even tried flashing the international version.
9.5.9.GM31CB - T-Mobile Firmware seems to provide the best battery life for me.
9.5.10.GM21AA - International Firmware saw more drain, idle and with usage.

Pretty impressed. 3rd day of ownership, not rooted get. Gm1917 on WiFi. 40% battery yeilded me over 6 hours sot.

[Q] Cell Standby Bugs? It Is Draining My Battery

I am on the latest update, which is 10.3.5.0 (PFGMIXM).
Right now the 'Cell Standby' is killing my battery more than the screen.
With my Redmi Note 5, I can get about 8 to 9 hours of SOT.
But with Note 7, I think the maximum SOT would be about 7 hours only, and I have to recharge it.
The question is, is it a bug in the latest firmware update, or is it related to the hardware?
What can I do, to 'fix' this?
It kinda mess up because I can easily get 2 days of battery life with Note 5, but not with Note 7 which is using a better CPU.

Really?
NONE of you guys have this 'problem'?

It seems to be some bug in the signal connection, maybe in a next att can solve, try a hard reset, switch to beta rom.

Have you disabled dual 4G? Changed to use 2G network? Go through Sim settings for optimal battery performance.

Hey, thanks man. I will try that setting later and I'll let you know if it does bring improvement to the battery life.

Did this ever fix your issue?

ye man got the same problem. I put my phone into airplane mode, turned on battery saver, went to sleep but still charge consumed 4-5% after 7-8 hours of sleeping. This is ridiculous! Got the problem in 4x now in rn7. What the hell is going on with redmi

I would backup your data and factory reset the device.
I've heard of people having this issue with the new 10.3.6 but not 10.3.5.
I'm on 10.3.5 now and refuse to update since the battery life experience I have now is perfect.
If you haven't already, try factory resetting the phone and report back

I have the same issues. I changed from Xiaomi Mi A1 to Redmi Note 7 and the difference in battery life is ridiculous even though in comparison test Redmi Note 7 should last quite longer than my previous phone. Currently cell standby consumer 67% of battery whereas my screen only consumes 21%. My version is MIUI Global 10.3.4 and I have the same issues, cell standby consumes a lot of battery. Tried a solution that I found regarding changing mobile services to LTE/WCDMA (it defaults to LTE/TD-SCDMA/UMTS which includes chinese networks) it helped a bit but still the problem is that after restart it doesnt keep these settings

7hrs is not a bad SOT for RN7, the reason RN5 lasts longer is because SD636 consumes less battery than the SD660, I also changed from a RN5 to a RN7 if you're wondering.

Hello guys!
I bought the phone yesterday and also have the same issue with the cell stand by: it started to waste 60% of my battery. Now it at 42%.
But at the end i realise that all that stats are in relation with the beautiful graphic that shows you the discharge of your battery since the last charge...and that is the key. For example now my phone is at 59% of batterfy since last charge this mornig, 11h 30min hours ago (i leaved home with aprox. 92% of battery)
Im thinking that the percentaje of battery drained by the stand by is okey and we dont have to worry about....because its only saying that in the 11 hours since last charge, the 42% of that time the phone was losing battery because it was on stand by.
But well maybe im wrong....
PD: i also have 10.3.4.0 global version of MIUI and i also put my network type of connection to LTE/WCDMA

Try going to about device > tap internal storage until the network menu pops up > SIM 1/2 > Change bands to LTE/WDCMA
A similar bug appeared on the Mi 8 Lite and this fixes it there

both phones have 4000mah battery and similar FHD+ screen.
the difference is: RN5 has SD636 BUT RN7 has SD660. both fabricated in 14nm but SD660 is way more powerful. SD660 has better GPU and higher clock speed. that's why RN7 uses more power compared to RN5. Unless you underclocked the CPU and GPU, there's no logical way for RN7 to have a better battery life compared to RN5; if they're on the same OS and have same usage.

You are lucky to have so little cell standby drain! I'm over 80%...
It is related, to the SIM, maybe the baseband/radio.
Changing to custom ROM doesn't seem to improve either, I'm testing havoc ATM.
I've opened a tread on the miui forum, but had no replay's. I'm not yet allowed to post link...
Edit: 1.5%/hour idle drain with Havoc OS. Going custom doesn't improve sadly.

On nights I always turn on airplane mode...and the drain is the same, so, is not a signal issue related thing

Is it possible that airplane mode doesn't switch of the radio? Cell standby is "(cell)radio idle" IMHO.
As an update:
I had a private conversation with one other owner on an other forum.
He measured different SIM-s idle drain and found practically the same result as I'm.
-Telekom voice only: 0.3% /hour
-Telenor data only: 1.2% /hour
-Telenor voice only: 0.4% /hour
-Digi voice/data: 0.3% /hour
Note the two Telenor SIM-s, they are under the exact same conditions/LTE band/coverage/signal strength/ect...
So if you use a double SIM setup, with a 2nd vampire SIM like the above Telenor one, You could easily criple your 5-6 day stadby time to 2 days.

What's up with the terrible battery drain when idling?

I've had the RN7 for like 2 months or so. My previous phone was a Samsung Galaxy S5 which I liked quite a lot & ran Lineage 16 on it for the last 3 years. On that ROM I got used to having literally 1% of battery drained on idle at max & could leave the phone on the last percent of battery left for 12h & it wouldn't turn off. Now, being on the RN7, things are different... I'm on a 3rd ROM (Syberia -> LOS 16 by lmc -> LOS 16 by AmulyaX) by now & have to say that even compared to MIUI, the idle battery drain is just... abysmal. How is it possible for a phone with a 4000mAh battery to drain 7-8% of charge during less than 10h idle where a phone with a 2800mAh battery could literally last half a day. Because of that, my overall SOT also takes a hit as on MIUI I was easily able to achieve 8-10h SOT, where on LOS or any other ROM I struggle to get 7h. Am I doing something wrong? Are all the ROMs for phone just straight up trash? Is there some bad omen acting on me? I just want an answer to why the battery drain during idling is so awful... That's just straight up unacceptable.
P. S. No, I do NOT care about undervolting/underclocking the CPU or GPU as I never had to do that on my previous phone.

I was also thinking about that. I see many people claiming like 11+ hours sot on this phone (custom roms and stock) but I can barely reach 7h. My last phone had a 3500mAh battery and would last a full day of use, but this one with 4000mAh makes me look for a charger during the day. Really weird.

Same here. Actually i had the same disappointment with my redmi note 4 i had previously. My old phone with 2300 mah battery lasted much longer. With both redmis my battery is dead at the end of second day with 3-4 hours of SoT

So... Few days have passed since the last post & in the mean time I charged my phone like 3 or 4 times. In the last few days I noticed something curious regarding the battery idle issue. I lost root like 2 or 3 days ago & from that time I noticed that the battery idle drain has DRAMATICALLY improved. It seems that somehow having Magisk causes battery drain (could it be related to the System On Root thing on our phone)? It could just be a coincidence that this happened at the same time, but from when it happened, my phone hardly drained a single % of battery when idling & I was actually surprised. Personally, I don't really need root anymore as I don't use apps that need it other than starting them for the first time to i.e. restore my apps backups.
Hopefully someone will do something with that info & maybe will solve the idle battery drain issue

I have the latest Atom ROM and the battery drain is ok! After two days i install magisk just for root and I clearly see the battery drain is a little bit more high !

Did you unroot your phone while using custom rom or turned to stock rom bcoz I'm planning to install pixel experience custom rom and does it have any battery issues?

In my experience battery performance in PE 10 is the same as in MIUI 11. I only need to go for the charger for like, once a day. Even with Magisk installed.

I've played around with the CPU settings in Kernel Adiutor like 2 days ago & then used my phone the way I always do. From the "results" I've gathered, it seems like my combinations of settings has made the phone enter deep sleep where as before that state was unused (as reported by KA). I probably didn't discover anything ground breaking or revolutionary, but with the settings I've changed, I still have the same performance as well as good battery life & great idle (literally 0-1% drain over night even with apps running in the background).
I will list just the settings I've changed in Kernel Adiutor to not spend a lot of time on writing each separate option for no reason.
CPU:
Big governor: interactive (you may fiddle around with it if you want to)
LITTLE governor: powersave
boost input interval: 0ms
CPU hotplug:
Minimum CPUs big: 1
I/O Scheduler:
Internal Storage scheduler: noop
Virtual memory:
Z-RAM Disksize: 2040MB
Now, as I said, I'm sure these values aren't revolutionary & my issues may have went away on their own, but you can always try for yourself & report back if anything changed (don't forget to save your current settings)

I'm on Havoc 2.9 and still play, but...

if you want to save you bettry in your phone, use the option of the battery saver if do you have,
if you dont have, try battery saver apps in your phone
