48 Hours of Battery Life on Epic 4G

I got 48 hours of battery life this past weekend (2 full days) after reworking my phone on Friday. I actually got 24 hours of battery life one day, when I first flashed the phone a couple of weeks ago, with Light / Moderate use. I am running the Bonsai4All ROM. I had been running it previously but had flashed back to stock due to an issue with Wifi, that I thought might be related to this ROM. After further research I found the Wifi issue was NOT related so I decided, since I liked Bonzai so well, to re-flash and keep it.
Here's what I did:
* From Odin I flashed to the stock ROM.
* I flashed to DK28 via Odin.
* I loaded Bonzai4All_Leafless.zip, ext4-format_njournal.zip and kernel-EXT4-RFS-Bonzai.zip files to my sdcard.
* I rooted my phone using the OneClickRootCWM3.zip.
* Restarted my phone in Recovery Mode to update CWM to ext4.
* Flashed Bonzai ROM and started phone.
* Installed my apps.
* Restarted my phone in Recovery Mode and ran Reboot Recovery to get to CW 2.5
* Flashed ext4-format.
* Flashed Bonzai4All.
* Flashed Kernel-EXT4
* Restarted phone.
At this point I had a clean install and all apps re-installed via Google. Then I turned the phone off and fully charged my battery. I Bump-charged the battery 6 times (6X) to get a full charge (something I found in another post). Before I turned the phone on I booted into Recovery and Wiped the Battery Stats. I restarted the phone and followed these steps (also something I had found in another post in the forums regarding battery life).
* Turned off bluetooth when not in use.
* Turned off GPS when I didn't need it.
* Turned screen brightness to automatic
* Turned off 4G receiver since I was out of 4G coverage area this weekend.
* Turned off synchronization. Only enabled it throughout the day to sync.
* Left Wifi on as much as possible since I was in an area with wifi all the time.
* Toggled Airplane mode after I rebooted the phone. (the post stated it was a "stupid bug")
* Killed the OmaDrmConfigService process via Settings > Applications > Running Services.
The phone was used lightly over the weekend. I used Bluetooth when making calls and only syncing about four times a day. I also did a few text messages. I fully charged my phone yesterday and am using it more to see what the battery life is with Moderate use. At this point it has been unplugged for 20 hours and still has 64 percent charge.
I took pictures via Shoot Me every 12 hours. These pictures are real, they have not been tampered with. Don't know what anyone elses results have been but here are mine.

Ehh..With light to moderate use thats not too impressive; btw..the "bump" charging isn't good for your battery. Theres a reason why it doesn't fully charge; because it's not good for the health of the battery.
Sorry to burst your bubble man ^-^ I've gotten 36hrs on moderate/heavy usage.

OP, Did you change your Wi-Fi advanced settings to "never sleep"?

That's why I posted this...wanted to know what others were getting from the battery. I'm aware of the bump charge issue and this is a one-time thing for me...don't have money to replace it...hehe.
What are you doing to get 36 hrs?

Everyone should just get an extended battery and not worry about battery life anymore. I run everything at their optimal settings and the phone lasts forever anyway. Brightness at max all the time, no juicedefender or any of that nonsense. Its awesome. You can leave GPS on contantly. Who cares, you got plenty of battery. And if you absolutely need the battery to last you can just tone down some things and make it last for days. Longest I have gone is:
but I hate running my phone like that.

I bought the 3500mah one from ebay. They go for like 12 dollars now. They are not actually 3500mah, but they certainly give a giant boost over stock. They are probably around 2600-3000mah realistically. I have a review in the accessories section. The name brand batteries might be better, but no one has done a objective test comparing them yet and for the price its hard to beat the generic ones from China. People are very satisfied with the Yoobao 2800 mah batteries as well, and those go for around 20ish dollars shipped on ebay. Both are the same thickness and add a little bulk to the phone but you get used to it almost immediately.

google this: Seidio Innocell. they have a 3300 mAH battery and i believe they might have a 3500 mAH one as well. so far ive seen nothing but the best reviews for this brand on newegg, amazon, as well as anroid central. theyre a bit pricey, but im not going to let that stop me from using my phone fully without fear of being too far from an outlet

Save your money and buy the generics. All battery manufacturers blatantly lie about their mah ratings, Seidio included. The only mah ratings that are genuine are from OEM batteries. That Seidio 3300 mah will really be around 2700mah. The criminals even have the balls to charge 6 dollars extra for the cheapest shipping after making you pay $75 for the battery. Buy the 12 dollar generic 3500mah on ebay which at a minimum will get you 2400mah real life or go for the 2800mah Yoobao which will probably get you around the same for $20ish. The generics blatantly lie on their ratings while manufacturers like Seidio and Mugen cheat on their ratings. Either way, you don't get the battery you paid for and at least with the generics you pay 7 times less.

I have no idea how long my battery lasts and frankly don't care as I have 4 of them. Just for the record the OP's method of installing Bonsai! is a waste of time IMHO.

Wow guys...
OP I just wanted to say thanks for posting the steps you took.. Not everyone is going to agree on the best way to do things. but it is good to see all the different options and opinions..

Same. I can't wait until the 2.2 source is leaked. Gonna have my phone overclocked and set for Performance in SetCPU, screen brightness on high, etc, while still having enough battery for a day.

Top Nurse: This was done before they released the new version.
muyoso: I ordered a two-pack generic 3500mAh with charger last night ($26). Again, I had been looking at them but wanted to hear from someone who had used them. In regards to your last reply, I also had my phone overclocked and set for Performance in SetCPU, screen brightness on high, etc, the first time I flashed Bonzai...got 6 and a half hours of battery life and only made ONE phone call...LOL! I've had almost 30 hours of battery life with moderate / heavy use after I posted the original thread, so I've been pretty happy. I'm looking forward to the extended battery.
Thanks to all for the input.

I didn't know that to be honest. I was given the impression that a lot of the generic brands seem to have a shorter life even with comparable mAH ratings. I also read amazing reviews for this specific brand even on here. I'm not a fan-boy or anything, but I've been trying to find a decent extended battery for my epic as well. However, I cant go out and spend my hard earned moneys without doing some research and so far ive read that this is one of the top brands. But now after reading your post im not so sure about what to do :/

The reasons to buy the Seidio is that you know you are going to get a perfectly functioning battery and that the battery might last longer than generics.
The reason to buy generics are that they are cheap as hell, but you may get a dud apparently, according to a couple people in my accessories thread, and might have to exchange it with the seller.
Either way, no battery other than an OEM battery will be at the rated capacity. I dont know how they are able to claim mah ratings that their batteries simply cannot reach. I mean, I know how the generics can do it, they are based in China and they can claim anything they want without retribution.
I recommend saving your money and getting a generic or even a Yoobao branded battery, because even if it does lose the ability to hold capacity 50% sooner than the Seidio would, you can just buy another 5 and still have paid less money than the name brand one.

I got 38 hours earlier with 3 hours and 42 minutes before i decided to plug it in at 9 percent
I'm on stock dk28
I don't have 3g on because in my house I'm by wifi, outside I'm blanketed in 4g and I noticed that since I took 3g off, my cell standby doesn't even show up in the battery percentage usage so I'm guessing that added to my battery life lol

These 4 are probably the biggest drivers. I've gotten nearly 36 hours out of the phone before with light use.
The constantly waking to sync is a large drain in Android.
Also, I notice the WiFi radio in this phone practically sips power. The 3G radio, on the other hand, tanks the phone like no other, moreso than other phones (and all the reviews seem to confirm this by the talk time comparisons).
That and using the display in auto brightness. The display sucks down quite a bit, despite Samsung's claims to its power efficiency.

See my post above
I got those results with the brightness set to manual (usually I have it at 50-70ish%, putting it up to 100 when watching videos and viewing pics) and the auto sync on
I think it has to do with certain kernals and stuff? Idk but I don't think its worth gimping th features that make it a "smartphone"...

[Q] Nexus 4 on order, arrival soon, what can I expect ;) ?

So, they have apparently sorted out the stock and supply problem. I <cough> borrowed the wife's credit card and have placed the order.
They say it will ship in 1 to 2 weeks, I can live with that.
The light-hearted question I have is, once I've gotten over the excited rush of playing with the phone for a while, what have your experiences been? Good or bad! I've heard that the battery life is not great but to be honest I am not so bothered with that. I have a charger and work, and home, in the car - I can even charge it at the pub/bar I go to

Keep an eye out for issues worthy of an RMA. From there, the only thing to expect is awesomeness. You'll want to calibrate the screen color and gamma, though.

Has battery life been that bad? Because I just ordered one myself to replace my wife's 3GS.

yes battery life is very bad on this device. in sleep/standby its great. but when you do something, it drains battery very fast. just 5minutes use and at least 10% are gone.

Utter tripe. You either have a rouge app, or you have the brighness turned up full or something else stupid.
I easily get a full day out mine with moderate use. It's about 50%-60% remaining when I get home in the evening from work.

I got around 3 hours of screen on time and a full 18-20 hours standby on stock rom with the usual useage of whatsapp and gmail syncing, with web use and texting etc, and now on custom rom, I am getting up to 4.5 hours screen on.
So, battery is good, phone is super fast and smooth, camera is great if you take time to learn how to use it and especially with HDR on and a bit of post picture editing. Only down side is music volume and quality which is average at best. In my opinion.

Thanks for the feedback. I just hope my wife can make the transition from iOS to android.

I think depending whether you are on WiFi or HSPA will make a huge difference for battery. From what I understand, when using HSPA, the standby battery life is horrible.

The screen is usually the single biggest threat to your battery. And the N4 can get 4-6 hours of "screen on" time depending on use. As others have said, it can be on standby for 15+ hours, but you can completely kill the battery in 4 hours or less if you are using a cpu intensive app.
Custom roms and battery saving apps can def help out though.

I ordered mine at 3pm on wednesday and it was with me by 3pm on thursday .. so slightly quicker than the 1-2 weeks they quote!

Unlock the boot loader, doesn't matter if you decide on staying stock or what. Having your boot loader unlocked right of the bat allows you to keep your apps if you do decide to root /flash.

You'll sadly probably find that the screen is *uneven* in it's tint (yellow probably) and brightness. Because it's uneven, "calibrating" will help a little maybe but will not fix any issues with the screen. On the other hand, with luck (which I wish you) you may find that your screen is pretty much perfectly uniform in brightness and tone top to bottom, left to right. (Check using the Mail app and minimise the keyboard) I've had 5 so far and none of them are acceptable to me. Otherwise the phone is truly incredible in use. Buttery smooth, responsive, great. The screen very generally is amazing too. It's just not even as it should be. Let me know how yours is - i'd be interested to know because if yours has good uniformity I'll order another. Good luck!

My drain is 1% per hour and I get more the 4hs screen time. Please, review your device and stop giving false statements.

How much do you believe turning off the data and just running the voice will save battery life?

Well expect battery drain issues (msm_hsic_host wakelock).

Poor battery no matter which rom

I've been using several different 7.1.2 roms and battery life has been atrocious. I use wingoku 4.1.
I pair my smart watch to it but even when I use wifi (no bt) its bad, draining quickly, last checked about 22% per hr. Even with screen off listening to podcasts it still will drop a lot more than it used to.
I really don't have much in terms of stats. Honestly I don't obsess much about it normally but now its noticable.
Aside from suggesting another rom & kernel, would I benefit from formatting data and starting over?

Install accubattery and run it though a few charge cycles, it will be able to tell you the life left in your battery, it's possible that you have the same issue many of us have had with a degradation of the battery.

Yea. Thats my biggest fear. Ive replaced small parts before but my eyesight isn't as good as it used to be so Im afraid I might mess it up. Plus I'll need to buy a heat gun.
I'll be more than a little pissed if the battery's shot. This phone is barely 14 months old. Either give us a decent battery or make it replaceable.
Thanks for the info btw. I just installed the app.

Update--Im switching things up a bit. Recently I made some changes and this time I flashed a new rom without some of those changes.
1. I had switched from Action 3 to Nova
*HIGHLY doubt nova is eating up my battery so Im still using it BUT I did remove a widget that has weather. Since I keep phone on device only location, I think theres a chance its always trying to find my locale and consuming battery.
2. I didn't add a gov profile yet.
3. This is the first time in about 4 or 5 rom flashes I didnt flash CTT Mod.
* Again I doubt this is causing battery issues but Im gonna hold off flashing it. No throttling thus far.
As suggested Ill be monitoring with accubattery for a few cycles. But been using my phone about 90 mins this morning (at least 90% of that time actively using with screen on) and I've lost 13%--a huge improvement from yesterday.

Accubattery for the proof. New battery for the fix. You could always buy online and have it installed locally. Read up on where to score a good replacement battery, rather than another dud.

Best to let it run below 20% at least and then fully charge until the APP tells you the battery is full- not your phone. Don't unplug until Accubattery says it is full. What you will observe is that the phone will continue to charge for 45 minutes to an hour past when the phone itself is reporting 100%. You will find the estimated capacity under the Health tab. Once or twice below 20% is enough to get a close approximation. After that it will move a couple percent max. You will know soon enough.

Well it turns out my battery is in need of replacing.
I let it run down like you said. I was going to go further down but once it hit 20% my phone turned off. I plugged it in, opened accubattery and it said 46% under health.
But I just checked again after charging to 100% and it now says 63% (2182 mAh total capacity).
I checked my imei on the Huawei site and my phone is 3 days out of warranty. Im hoping to get them to fix it.

Well sorry to hear that. Good luck to you on the RMA route. If not, the Cameron Sino brand replacement is a bit more expensive but includes a working battery temperature sensor. It will make your phone like new. Note in the thread I referenced above, some parts may get scratched/cracked depending on the skill of the repair person. They aren't expensive so it you are intending to keep the 6P for a while longer, it may be worth it to buy those just in case.

Thanks for the support! I checked that thread and didn't see specific parts (inexpensive ones you referenced) If they're listed Ill look again. It doesn't seem too daunting. I was able to replace the screen on my son's WiU controller. Those were very tiny parts and YES--I did snap off a clip, however I was able to fudge it and it's still working about a year later.
Far as RMA, does anyone know if they replace it with the same crappy stock battery? From my perspective this seems like a clear case where a recall is in order.
But if its the same battery, Im just setting myself up for the same problems 8 to 12 months from now. Even if I buy a new phone Id still want to sell this one and thats not as easy with a crap battery. Plus theyd have my phone for x days so Id need to find a temp phone in the meantime.
Don't mean to jabber on...this sucks.
Oh yeah...cuz it was after hours I sent an email to support last night. Do you think Ill get a response? Or should I just call when I have time to be on hold?

Spoke to a clone at Huawei then asked to speak to the clone's supervisor (wasn't sure if clones had supervisors--they do. But the programming is identical.) Long frustrating phone call and they aren't going to replace my battery because its out of warranty...by 4 f#@&ing days!
I told them they lost a customer for life and I was being 100% sincere. How could I ever buy from people who thinks it ok to sell defective crap, know about it, then do nothing to make things right?
I'm gonna replace the battery on my own. Whether things go good or terrible, one thing is certain--itll be the last time I ever replace anything on any product made by Huawei.

battery.

it has been months now having to deal with this issue.
i really love my 6p but I've got tired of having to charge my phone every three hours. it shuts down when recording video when the battery below 50% or giving the CPU a hard task like searching a long excel sheet. i cant open Snapchat when below 50% fearing that it will shutdown and its not may or may not it will shutdown .
i don't think its a hardware failure because when it happens twrp boots up just fine but cant mount data and it shows the real percentage. while ROM shows 1% and shutdown. it happens with all ROMs even the stock ones.
I live in a country where there is no support from google or any hardware store ( they don't even know the name of the phone ).
this issue have put me in many awkward moments I've waited for a long time towards a solution maybe that's it. and it is time to move on ??.

Its a hardware fault, as in as much as your battery needs replacing. Well known issue where the battery degrades causing this issue.
You could install Accubattery and do a health check to conform this.

i really love my 6p but I've got tired of having to charge my phone every three hours. it shuts down when recording video when the battery below 50% or giving the CPU a hard task like searching a long excel sheet. i cant open Snapchat when below 50% fearing that it will shutdown and its not may or may not it will shutdown .
i don't think its a hardware failure because when it happens twrp boots up just fine but cant mount data and it shows the real percentage. while ROM shows 1% and shutdown. it happens with all ROMs even the stock ones.
I live in a country where there is no support from google or any hardware store ( they don't even know the name of the phone ).
this issue have put me in many awkward moments I've waited for a long time towards a solution maybe that's it. and it is time to move on ??.

I installed a new battery and used battery calibration from the play store. It's working like new again.

I just got my new 6p battery. I can confirm that I just get 1hr of screen on time and it will shutdown. I live in asia and There is no stock of the 6p's battery everywhere here even in Huawei stores and service centers. I got mine from an online site and have it shipped to me. It took a while but it was worth it. Its like new again (bought this device 2nd hand and already have the degraded battery).

What batteries did you guys buy? I have battery issues. Phone dies but twrp shows another value. Sometimes drops by 2% instead of 1%

There is no more original battery for our 6p almost everything that is being sold is a chinese knockoffs. But I got a Beltron Battery. I also like the cameron sino (good reviews) but the price is 2x the price of beltron if when i ship it to my country. But, So far no issues. 1hr 45mins SOT and i still have 70% (Fb, YT, Web browsing, instagram and etc). Today is my first day of using this battery. Fingers crossed.

I've never heard that one. But I've heard I've had to be careful with sino as most are fakes now. But I've also heard good ones about Cameron sino x longer? Or something.
Very much would appreciate your advice on this as I don't want to pay for a fake. As I plan to get a new charger, battery, screen protector and case for it. But with the battery as it is now. Wouldn't be worth it

I suggest Beltron like mine, most of the batteries doesnt have any temp sensor. It doesnt bother me that much. I suggest using a 1A charger. Slow charging but it doesnt stress the battery so much like the OEM charger. My wild guess is that the charger is the reason why the battery degrades so fast. Good luck with your 6p!

Agree... but what does Accubattery say your battery capacity is? 1st day feel of the pants is feedback, but having data would be better. Run the app, and after a few full charges let us know how this battery compares to the one it replaced. You *may* have found a great replacement. Thanks.

Ill download the app again. I always forget using that app. Last night i charged it 30%-100% in just more or less 3hrs using 1A charger. i was asleep that time. Today I'm using the phone non stop. Off wifi and off cellular since i have a dedicated daily driver for my social life using this device just for entertainment. Today I've been reading manga using an app non stop @ 50% brightness. Here are the screen shots of my battery in settings. I think its good. Ill return with accubattery data later

Any links for recommended battery instructions?

My wife had the same problems and got a Pixel.
I ordered a new battery for around $20, put it in and now it's like a new phone. I swapped out the Sim card from my Moto z and now it's my daily driver. By the end of my shift it's still at 80%

I bought a brand new Nexus 6P and have had it for a month now and I must say, coming from the LG G5, its a damn shame the 6P's battery doesn't live up to the potential some phone batteries do. I would recommend doing a health check for your battery once a month at least, it's what I do to keep an eye on things. There are some good apps for monitoring your usage and longevity quite accurately.
Nevertheless I still prefer my 6P to the G5 :silly:

If your want an OEM battery here is one https://goo.gl/jmYfn9 the seller runs out but seems to get more in. I bought this one and had five and a half hours screen on time when I plugged in at 8% battery left. Mine was shutting down as soon as it hit 20%

I have to object to the that factor that the battery on the 6p doesn't live up to its potential, well I'm making a statement out out of that comment, I bought an replaced my own battery, even went as far as adding new thermal paste in the places required, I also have my device rooted an pretty much battery mod central on my device, I have had it for 5 days on deep doze settings an it's at 68%. I had insured my journey with complete overall satisfaction, I have added a 3600 an it came 2 days after I Ordered off Amazon, for 15$ free shipping, can't beat the fact is the way a device should run, no just a nexus 6p, I mean ll devices, if you can oot it when your phone is new, you can max your battery potential to the extreme, if you've had the device like me for 3+ years, every battery saving option I went through trial and error Makin that thing last for 3 hours if it was rooted with doze settings and lasted an hour max if not rooted. So I went the do it youself an learn something an it wasn't hard one bit. Charged It till full an turned it on an let it do its thing, I can't tell you how many of you need to change your battery out an buy a new phone. let's be clear an unrooted phone will never exceed battery life for the reasons of the hogwash they add o it an cause it to drain, if you eliminate the drag you'll get your full potential on battery life and only 15$ than forking out 500$ on a new device, work smarter not harder. Seeder, amplify, greenify, power nap, servicely, naptime, xposed, better battery stats, tasker, appcontext, powersving.apk,magisk doze mods, I recommend them all on magisk even if they are repoed, fix the prop for the present time if you know what your doing, Lspeed Is a great tool to have, I use elementalx an tweaked my settings for battery another great tool for battery conserving is [All+ROMs]+Galacticâ„¢+DeepSleep+MOD+[Super+Battery+Saver], find an flash it in recovery. For all devices.
If there are any questions on those apps or have any fed back let me know. Good luck.

part 2 fine tuning the battery.. 7 plus hours SOT

This should really help your screen on time note 20 ultra

7 hours should be the minimum out of the box for a very expensive flagship handset.
I have tweaked pretty much everything and still get around 5.
Emailed Samsung today for a return. Useless handset.

Ever think that maybe you've got a screen time problem? If you're on your phone for 7hrs a day it's time to put the damn device down [emoji1787]

It's not per day, it's per charge. So if you're only a moderate user 7 hours ST should give you a couple of days. My phone boots up at 7am and is dead by early evening.

My phone does 2 days easy if I'm at work. Otherwise, sure I probably have to throw it on the charger around 5ish because I've been facebooking and reading the news, I'd say it's far from useless anyways. And while I'm at work in usually using the Galaxy buds to listen to my podcasts [emoji1745]

It's kind of weird how a lot of people on Exynos versions are getting seriously bad battery life.. The other day I asked my daughter to watch all of her shows and stuff on YouTube on my Note 20 Ultra and asked her not to put it on the charger for any reason because I wanted to see what kind of screen on time I could get and I'm seriously getting close to 15 hours of screen on time and I am posting pictures below so people don't think I'm full of it.. At 24 percent battery life left it said I still had a little over 4 hours left and the total screen on time was 10 hours 37 minutes so if she had stayed awake for another few hours it would have been around 14/15 hours without a single charge!

I stopped worrying about screen on time 3 devices ago. Just use your phone normally as a normal person.

That's easy for you to say but some of us have to work and we can't be near an outlet all the time and we need to know exactly how much time we have available for doing important things.. Also, people who worry about their battery life doesn't make them "abnormal" like you're low key saying (Just use your phone normally as a normal person.")... It's great and all that you don't care about your battery life but this website is for help and other things so if you're not going to offer any solutions or anything of value then maybe you shouldn't say anything!

The main issue is that most of us (some long time Note users) are buing the phone because it is considered a powerhorse phone and advertised with a battery that "lasts a day". Most of us are using it like a normal person, that is one that use the phone in his/her daily tasks from browsing to mails, chats, watching videos or shooting photos or editing documents. Because THAT'S why we bought a Note and not a...dunno iPhone for ex.
And seeing that battery isn't in fact lasting a whole day on a 1300 phone we're "a bit" disappointed (and I was extremely polite saing that)

Seems Samsung is catching some heat over it's two chipset variants... again.
They need to stop doing this two chipset crap... Samsung is more fragmented than an old lady's Vista desktop.

Nice move, pay 1300 bucks for a smartphone and don't use because you want it's ****ty battery to last...
Still, the battery drain will destroy your battery, specially on exynos version

If you're on your phone for 7hrs a day and most people average 8hrs at work (obviously you use your phone at work) that leaves you 9hrs plus an hr or 2 (because your using your phone at work a bit) left to get home, cook, eat dinner, cleanup and sleep, I'd say your wasting a lot of your life. At this point the damn batteries have gotten good enough I'd say [emoji1787]

The Exynos 20 U is far faster than my 10+ with better ram too.
My 10+ was running hotter than the 1 ton deep fryer on the USS Missouri at one point.
It will take some time but you can get it running cool.
Nominal idle current should be about an average of 150-200 ma. Otherwise something(s) is dragging it down.
Get PD MDM and proceed... you will need to develop a good level of proficiency before you see lasting results.
*Bah-ha-ha-ha*, excuse me, I meant to say fun times are ahead
One reason I refuse to migrate to Q is I put some serious time into this system to get it optimized.
This 10+ was a real wanker... sure the 20 U and Q will be "better".
