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.

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..

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"...

Has anyone seen battery life improvement with a Seidio battery?

Was thinking about getting the Seidio Innocell 1600mAh Slim Extended Life Battery. Wanted to know if anyone thought it was worth it?

I just ordered mine last night after Froyo killed my battery life. I'll keep you updated how it works when I get it

Ok thanks, please do. Looking to get it for exact same reason.

100mah isn't worth getting another battery, IMO, unless you just want a second battery. that's such an insignificant amount of additional stored energy, I doubt you will see much improvement, unless your current battery was starting to fail.
just my 2 cents.

Just got my Seidio in the mail yesterday. It is slightly larger than the stock battery and the rear cover is a little tougher to get on. When I say tougher i mean you just have to move around the phone and snap in every section with your fingers. If you stare hard enough, you can see a slight bulge where the battery is. As far as the battery life, so far it's only been on a couple hours in the morning and does seem slightly better. It seems like it might be about 5% better than it was before. They also say that it should get a little better after 5-6 charges so we will see. I doubt I will see a huge increase, but when your battery sucks, every little bit helps

I got the seidio 3000mah battery and love it!! The back plate isn't bad at all (proportional wise) and it gives me a good 2 solid 10 hour days of heavy data/phone use without the need to charge.

Secondary battery

Has anyone tried buying a non official battery for their MS2 and care to comment or recommend any? Im going on holiday to france and i know my phone wont last a whole day without charging, so I was thinking of buying a second battery.

I read in another forum that using a non-Motorola battery displays some kind of warning. I'd go with an original battery.

using a non-original battery could have detrimental effects on your phone. there was a discussion on this on the forum of another phone. using a non-original battery could lead to leaks and other problems which would eventually lead to the warranty of your phone being voided.
stick with original motorola products. yes the battery might be very underpowered, but its the safest bet to ensure the longevity of ur phone

With a non original battery, the battery indicator of your phone shows a interrogation symbol. Also, it does not charge with the phone charger.
Sorry my analphabet english xD
@Motorola Milestone 2

bp7x 2300mAh battery

I 'm using a non-original battery . The MOMAX and everything's good ,it feels just like the original one except for battery tempperature sensor. the temp is always 26 in celsius

I personally have used seidio for my milestone and it works like a charm, its the extended 2800mah one it really performs like it should and not like how a lot of people claim thats its way less than stock! It does not always read it correctly but a quick reboot fixes that, like 50% after reboot would usually be about 70-80%. They way i used to use my phone (light to moderate level) would last about 2-3 days but after the extended I got twice that and some more. Just make sure you get stuff from the original manufactures either way and don't go for deals at amazon or whatnot as those guys might be selling either defected or not proprely stored stuff. Batteries are critical components don't go cheap on them! And no, my phone has not been messed up or had any leaks or anything and I have this for about 3-4 months now. The original battery degraded in about 6months if you have to compare.

That sounds promising, does the battery need to be charged with an external charger? And does the milestone complain that you are not using the official bettery

reebooting your phone to get the exact picture also works on the standard battery. my question is, does the back part which houses the battery heat up when used? does the phone get hot during charging? do you need a new battery cover for it? and besides the longer usability, have you noticed any other performance issues on the phone?

Actually the rebooting to get the exact picture is not the same here, a jump to 20-30% on a stock battery? I don't think so. No I never encountered any odd behavior with the other battery. No getting extra hot during charge or use, get the typical little bit of heat while using 3G and browsing like mad but that would happen on the stock battery too. Battery cover for a 2800? of course, that stuff is huge! its protrudes like mad! a quick heads up though, the extended battery for the milestone 1 and 2 can use the same extended batteries. Don't know about the droid x though. Anyways, no performance issues, no heat while charging. The back covers supplied by these after market guys are not the best quality though so if you are someone who loves dropping phones and what not would recommed getting a spare back cover from the guys you get the batts from.

No, I use my original charger and no complains or warnings by the phone. Not on the milestone 1 at least. In fact some times i use my ipod's adapter so no big issue. And it charges at the same pace as the stock, additional 1 hour or whatever. restart the phone to getting a proper reading as it shows 100% but upon restart its 70-80% since only the stock level is charged. I hear this app called battery left does great for calibration.

ALSO a thing to note, I only know of Seidio and Mugen to be relialbe after market battery guys hence their hefty pricing at times. The others claiming to have bigger batteries have cheated people with stickers and what not and usually end up underperforming and degrading considerably faster than burning paper! I remember 1USD batteries for nokias back in the day good for a quick one time run i suppose but these 1USD guys are now selling them with a better branding for like 20-40 USD.
Anyways Sedio and Mugen have facebook profiles and keep people posted on the latest on devices usually there, although its kind of sad since seidio have not followed through promised products at times.

Cool but as I suggested try and get them off the manufactures themselves as I have noticed some people complaining when purchased via 3rd party retailers.
Also another bud of mine had picked up one for the Nexus one, that phones back cover is a full one unlike the moto's and he too can vouch for the products positive performance. Either ways also check out some reviews from amazon.com for peace of mind.

After my first day of use I got around 11 hours of use before reaching 5%. Here are the usage statistics at 15%
https://picasaweb.google.com/105351366297036719015/DropBox?authkey=Gv1sRgCJna6ZH6hLKxzQE
Wifi was on most of the time, I was using my phone for the usual things. Occasionally checking socialfeeds, engadget, xda every hour or so and internet browsing I played 10 minutes of angry bids. Updated some apps and downloaded a few new ones.
Overall not a significant increase in battery life maybe an hour or so more from what I am used to.

Time to replace my stock evo battery ?

Its been a year since i got this phone and the poor battery has had nothing but heavy usage the the entire time. Im wondering how after 500+ charges a evi battery should be holding up and what the life span of it is till its time to replace after heavy usage and on quite a few ocvasions more than one full charge per day.. Old age is a ***** haha. Thanks guys

Unless you notice it's not holding a charge like it used to, heating up a lot, or swelling up, I'd say it's still perfectly fine.

First 75% or so just drops fast. 75% through 25% so so and the last 25% holds strong like the whole 100% used to. I wasnt sure if it because miks rom and heavier usage from 3.0 though?

U got the point there. U made up my mind. I hear u cant get one thats 2000mah that fits under the stock hood? I havent found one online, any suggestions?

Yea I wouldn't mind finding that battery too. I really don't want to make my phone thicker with the big extended battery.
We're comin from a pure power source.

Usually batteries typically should last a year (or longer) but when I used to work at tmo I found that they start to lose full charge at around 8 months; im only speaking for HTC batteries based on my exp w/ their devices. If you can get another one id say go for it.

Where did you pick them up from?

Check the thread in my sig.

just got my extended battery with the oversized back. So far its great. I keep the extra smaller one in the case. Pretty sure I can go all day now and do pretty much whatever I want. The back case actually fit tighter than the original

The era of wireless charging will begin soon...

New EVO batterys ?

Check the battery and see if its a 1500MaH...I think I may have heard they were, but I could be mistaken. Also your type of usage varies the battery life.

They have the same batteries which are 1500mah.
things that could be getting you better battery are
-Updates like 2.2 and 2.3 which improve performance and battery life.
-New battery, yes batteries get worn after a number of charging cycles.
-bad battery with your old phone.
-your old battery wasn't properly calibrated.
I'm rocking the sprint 2600mah battery they sell at the store, end up at 40% by the end of the day.(got it free) unplug at 5:30 am and plugs back in at 10pm every day.
That is with 10-15 phone calls, maybe 30mins-1hr browsing the web, 15-20 text messages and two hours of pandora along with 30mins of gaming( slice it and pew pew). With the stock battery I always ended up needing juice by 12pm. (On 3g, MAX brightness and 2 email accounts checking every 30minutes I think)

They do make batteries claimed to be 1900 mAh that fit in the Evo. In fact they're exactly the same size. Since a battery's capacity is linked pretty directly to its size, the general consensus is that the battery's ratings are being inflated. But having said that, a new battery will perform better than an old one (making it hard to compare if you're replacing an older OEM one), and they may even be somewhat better than a comparable stock battery. It just isn't likely to give you the expected percentage difference between a 1500 and a 1900 mAh battery.

I got them from here. It was a little bit thicker than the 1500mah but the back still snaps on fine. Noticed a bit more life but nothing to blow ya over.
