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

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 Xiaomi Mi Pad 4'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!

It was with MIUI . I have battery on 65% and after 5-6 days of stand-by I returned to it and it has been turned off with 0% in battery. It is terrible. MIUI is not optimised at all in the subject of battery . It is not very big supprise . I have had the same with galaxy tab 4 on stock. Once it consumed all battery during 2 days of stand-by.
If you want to buy this tablet and use it without bootloader unlocking with MIUI , please select other device.
I installed aicp and made my own optimalisations. I can see the result in WLD and on system battery graph. It will live month or month and half on stand-by now. It has a sense.
I voted 1 star , of cource this is MIUI raiting .

I dont have such problem and stock MIUI works perfect for me. No idle drains, bugs, or other problems. Battery life is very good, and all custom roms have some kind of bug, so no, i wouldnt recommend custom rom over stock rom. Also, some sellers preinstall custom miui roms before selling so you have play store preinstalled. So first make sure you have official miui rom and not custom vendor modified miui.

I am sure . Orginally packed by Xiaomi.
Edit.
Today I have the second pad 4 but this time not miui 9 but miui 10 stable and battery works noticable batter

Nothing to complain about on stock miui 10. It's not that I actually tested it but I have a feeling that it would last at least week on standby.

I was travelling and didnt touch tablet for 4 days. It only lost 8% of battery during that time, which i think is awesome.

Sorry, what is AICP you mention here ?

How it is with auto-off-timer? I'm use it on my Redmi Note 4 and it's great. So i can use my phone over 4 to 5 days with nearly 30% screen-on time.
Between 0:00 and 7:30 my Phone goes automaticly in deep sleep. After 2 years i'm absolutely happy with this solution.

I'm on MIUI 10.4 and can't find this option...

I think it's the Bluetooth that's draining... At least on mine. After I disable I can have it off for days and days and only drain a few percent .

I tried playing around with the Bluetooth but it doesn't help. It was never on by default so I tried with it activated and deactivated over a long time but I can't see any change.
My tablet version is the 3/32Gb WiFi only. What about yours ? It seems that LTE version has different behaviour.

For me Standby time is amazing / Mipad WIFI

What is your ROM?

Just got a Mi Pad 4 and I'm having the same problem, fast battery drain even on standby. I'm on stock MIUI 10.3.2. Any tips/workaround to address this issue? TIA!

Has been using stock rom for a few years without updating playstore and any installed apps and the battery life was great like still more than 50% after a week idling with a full charge. Playing around with the settings recently and turn on auto update on playstore and uninstalled some apps. Battery drain was almost always at 0%(turn off automatically) daily with a full charge and idling for the past few days. I totally regretted what ive done zzz

I'm testing idle drain after swapping the battery out. I bought the battery when I bought the device, but just got around to changing it. The device was out for 2 years before I purchased, so the batteries are as old as the device. It would last no more than three hours before. I also added a copper heatsink and thermal paste. I was about to get rid of it, until those changes, I'm on A11, and it's running really smooth.

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

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.

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)

P. S. I'm on LOS 16 by AmulyaX

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

Screen on time

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 S21 / S21+ / S21 Ultra before depleting the battery.
Then, drop a comment if you have anything to add!

Pretty damn average on S21 128GB Exynos version. Accubattery says max 6h on charged battery and it's pretty in line with my experience. Charged in the evening (around 19:00) and unplugged, I could only do 4 hours SOT before it died around 17:00 the next day.

I'm on 2.5h SOT. Same setup on p30 pro was giving me 7h of course it was without 5g and no 120hz but still it's a huge difference... let's see how it evolves

Previously I smartswitched and set everything up. I factory resetted the phone, SOT did not seem to get much better than previously reported but I think idle drain is a little better. I don't, however, have all apps set up yet and also changed Messenger to Lite, uninstalled facebook.

Battery life is poor on mine (Exynos) : around 2.5h SoT after a day of use, mostly in WiFi. I actually can't use it for a day even though I try to save as much battery as possible.
Initially migrated through SmartSwitch, I did a factory reset without this migration and still have poor battery life after 9 days of use.
I'm really considering returning the phone.

very bad battery usage... no idea what is eating at background of the device...

Just returned it, that's really not worth 700+€.

The Exynos curse strikes again eh? I vowed never to touch another Galaxy phone after a similar experience with the S20 last year.

It's definitely not as good as my previous two or three devices. Especially my last one. But that's not a fair comparison. Most people don't own those or even know about them (Chinese imports - flagship chips with high refresh rate displays too). I've only owned this for just over a couple days and idle drain overnight is too high. Actual SOT is average. Not terrible or awesome. Just about acceptable. My concern is, how it will hold up in the one year or more life cycle of my ownership, if this is its performance four days into owning it.

Hi, do you have sync on? and did you limit background use for apps and also put them to deep sleep?

120hz
Pretty average SOT

The following are On all the time:
WiFi
Mobile Data
Bluetooth
Location
Sync
NFC
Power Saving Mode.
I dont manually put apps in deep sleep, i just leave that to the system to decide.

120hz refresh rate
Power save mode off
20% battery left, battery still shows 3h50min left unfortunately have to recharge.

I noticed a massive improvement in battery life on my S21 when setting a Bixby routine to automatically turn off mobile data and location services when connected to known wifi networks.
You can also set a routine for auto rotate to only work when opening certain apps, this will save you further power turning off that sensor until required.
Enable wifi calling under connections if you struggle with mobile signal in any areas where you are connected to wifi. This will assist with less stress on the phones battery searching for a better mobile connection.
Also turn off fast wireless charging in more battery settings if you do not make use of wireless charging.
My standby battery drain with the above settings is now nearly non existent.

Improvement in battery life after August update on S21

Using battery saving mode, since I already use 60hz (to save 15%) and already put WhatsApp and Telegram in sleep mode (and many others in deep sleep). I still get push from IM.
I don't have seen any problem and got much more SoT then shown here.
Soon I post a full battery only print.
