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.

thanks for the info mate. ill do a lil more research and probably check it out myself.

Thanks for the info i have bought a Seidio Innocell Extended Life for Motorola milestone 2 from mobilefun £30.49 its the 1500mah version same size as original battery so no extra cover is required.

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.

is the battery meter being shown or are you getting an error message because i would like to buy one

No complaints from the phone about it being the incorrect battery the battery has been charged within/by the phone no external charger required. I got the 1500mah version from mobilefun I doubt it will give much more performance but will see.

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.

New battery... higher capacity than original???

hey all.
i am considering buying as new battery for my defy. the one i have is about a year and a bit old and batteries do tend to wear. i have come across a few on ebay that are higher capacity than original and am wondering if they will charge to full.

http://www.ebay.co.uk/itm/250992673...X:IT&_trksid=p3984.m1438.l2649#ht_2295wt_1142
i have a defy red lense and am currently running cm7 kang by fuzz i think it is (great job mate by the way love it it is silky smooth). i am considering giving the cm9 rom a try out shortly so would also like it to work with that rom.
so will these charge up to their full capacity or will they not? if anyone knows before i take the plunge can they let me know please
thanks

I've got a 3500 capacity one it charges to 100% then runs down to 0% but then stays alive for an extra day I've got rid of battery icon just wish I can get rid of flashing red light and the warning on lockscreen. If your rooted you can get battery calabrator from market. It works but not for the massive batteries. Hope this helps
defy cm7

cheers mate exactly the answered i was looking for. will get one of those above then probably the 2400 one or whatever it is. that will do me i all i need is an extra 12 hours or so. i may even go and get one of the external batteries as well as a new internal battery as that would be good for all my usb devices. cheers again bud.

No worries glad I could help.
defy cm7

Does anyone think it is possible to create a custom battd.bin which supports the higher capacity? That would be really cool

Might be an idear!
I will have a think about it.

I would support that. I wonder what is required to change the battd file for larger batteries

Hi,
as I found, battery calibration doesn't solve this, even not on the smaller batteries. I use a 1700 mAh HF5X battery in Defy. Somehow it's recognized as 500 mAh, and not charged fully. I have the same issue: battery indicator stays on 1% for a long time.
I tried every fix and kernel I've found but nothing worked yet.

After checking, I think those batteries aren't so good (except perhaps the 3500 one) ... give a look at this thread : http://forum.xda-developers.com/showthread.php?t=1828768
More, I checked other seller on ebay and everytime the same, whatever the seller : all the bad comments are about "high capacity" batteries ...
Good luck to find a good one

[Q] Motorola Defy (Defy+?) Battery Fix Please

Hi all and thanks in advance for any help/information/answers I may get. A couple of weeks ago I bought a Defy off ebay with a known problem where the seller had tried to flash with less than half power and screwed the phone up. After two weeks and lots of reading I've managed to get Phone working (after flashing a chinese sbf that put BL7 on it) with a cm9 rom on it. Only problem I have now is that the phone believes its a Defy+ when it is a Defy (green lens). Whenever I put a battery in (fully charged through wall charger) battery meter only ever says 80% (at most) and the phone doesn't seem to charge the battery. I have tried various fixes including red lens and cm7 zips but got no-where. Does anyone have any other ideas please?

Hi try Asking to walter79 maybe he can help you.

at present there is no fix. the phone is stuck as it is now until someone comes up with bootloader downgrade.
my phone i presume yours and a few other unlucky souls who jumped before looking have a device that wont charge and that doesnt register true battery stats. as a workaround i use two batteries one charges in a wall charger while the other gets used and i keep alternating them when i need to.
my defy has been like this for about 3 or 4 months. the only way to fix this would be to be able to downgrade the bl7 to a bl6 or below but that isnt possible as yet and too be honest i wouldnt hold your breath that someone will bring out such a hack considering the phone is pretty long in the tooth nowadays. you can however at least root it and install other roms such as euroskanks cm7. the battery still doesnt work but you can hide the battery icon and simply keep alternaiting the battery and if you have a red lense the camera and everything else works sweet as a nut. if i cared that much about phones i would have changed it by now but quite frankly i dont. as long as it does what i need it to (which in reality is very little) then i will carry on using it as it is and when the price of an xt890 has dropped to such a level that i can justify buying one i will send thew defy off to mobile recycling company.
anyways sorry to be the bearer of bad news but look at on the bright side... at least you can now give up googling and then flashing all the defy battery fixes (none of which work for this particular problemo!).

Thanks for the reply must admit I was beginning to think there was no way round this. Still no problem I only bought the phone to attempt the repair and then resell. Got four batteries for it so will give it to my daughter and sell her phone instead.

Battery drops from 30 to 0 in minutes

Hello,
I have a problem with battery, it drains normally until it reaches 40 or 30 percent, after that it suddenly start dropping rapidly until it shuts off in just a few minutes and acts like dead. I think this started happening after MM update, I've found several answers online but none of them is from an active Note 4 user but from tech specialist, suggesting it might be both a battery problem or a software problem too. Also, some people state that a new battery solved the problem, but also many of them bought the new OEM battery but the problem still exists even with the new battery.
Does any of the users on xda have the same issue after MM? I don't want to waste money for a new battery if it's not a battery problem. And again, I dont know if and when will Samsung release an update for this kind of bug if its a software thing... I would like to know if I'm alone with this and hear some thoughts on buying a new battery or no?

It's your battery!
Your battery has deteriorated to a point that it only hold around 70% of its original capacity.
I have 4 original batteries which 2 of them are new & 2 of them are old, deteriorated ones.
One of them only holds around 70% like yours & one of them holds around 90%.
The new ones.....they works perfectly.
They holds around 99%.
Remember that lithium batteries deteriorates through time whether you use it or not.

Thanks for your opinion.
Once it also happened that my battery level was showing 50% and in the middle of browsing, my display went black, touch keys working and display is completely black. Even after a couple of restarts and cache wipe from recovery it remained black after booting, while the screen was working properly on the boot and showing samsung logos and all. I assumed there's a voltage problem, but I still was not sure is it a defective battery or system not reading the level of it properly. Never happened before with any of my previous Samsungs.

I've got almost same problem as @ljubimci.
The only problem is that I bought new battery (from samsung shop, 100% original not fake) and it dies even faster then my old one
The bigest drops are when i use high demanding aps, especially camera (4k recording) then it can drop from 60-70% to 0 in "0 minutes". This started to happen to me on MM, so i downgraded to LP (5.1.1) Nothing changed... And at the end i've changed my ROM to stock, unrooted 4.4.4 (ANK4). Problem still existing End the last biggest problem of them all is that i've lost somwhere my receipt, so i can't give samsung my battery back ;-(
I know that to some people changing ROM's help, to some new battery help, and it looks like to me only xda can help Is there a possibilty that new battery is damaged, or maybe there are any kind of fixes?

I think that you bought a faulty battery

Is this battery consumption normal?

Hi all,
I just come with this Screenshots to know your opinion on the consumption of my s5. Honestly Im jealous of those people getting 4,5hours of SOT in a full charge. I believe I can barely achieve 2h. My phone is rooted, de bloated with smart debloater and uses Greenify (which has not provided me a noticeable gain).
I've seen a very big drain just after plugging off the phone (like 5 or 6%) in two hours without using it. Also everything I unlock the phone the drain is very fast. So idle state seems no to be the cause
What are your thoughts? Thanks in advance.
By the way, while writing this post I've lost 5% of charge.

Need a new battery I think and with the battery you gotta keep it cool, don't charge you phone and use it when its under 20 ℅. And the hotter the battery gets the faster it will discharge and if your charging at the same time the CPU will work harder to charge the battery and do whatever you want to do with your phone making it a double whammy wearing out your battery much faster than normal. You not supposed to let our batteries to go below 20 %. Well you can but don't use it at the same time your charging.

Thank you very much for your information. Any suggestion about a new battery? I've seen this one.
I've just plugged off from 100% and I got a battery drain of 5% just by speaking 15 minutes (no hand-free). I think it's a very big battery drain for just a small talk. I think that confirm your hypothesis of the wasted battery.
Is there any way to know the real capacity of the battery I currently have? It is just to know how far it is from its original performance.

I've checked on Go Power Master app and it claims 2520 (at 90%) mah in my battery. Is this confident? If so, I shouldn't expect a big improvement buying a new battery. What about using other roms or making a factory reset?.

How old is your battery? Mah rating and the rate it discharges are different you can discharge 2600 mah batter in an hour or 3 days depending on use and environment and conditions. Like I said before the hotter your battery gets the faster the disharge go same with the cpu the hotter it gets the more power it demands from the battery. And if your battery get under 20% fast charging comes. Into play as well which is bad for the battery as well.
If your dropping off that fast I think is a defective battery or over clocked cpu settings. My s5 did he same till I bought a new battery I last 8-12 hours of heavy use now compared to 4 hours. With a new battery I suggest a higher capacity but same dimensions as the old one they can be expensive but a bigger battery will damage your phone over time.
I have a 5600mah battery now by 5he way.

Oh my power app tells me I have 2520 too but I really dont....heh

Oh that battery looks OK I can't read the language lol just make sure its not refurbished or used and check out if u can refund it or not lol

My battery is from October 2015. It's the original one that came with the phone

Here is last report:
Despite performance is not the worst, do you think the difference with a new one is very big?

Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind
I myself lose the first ~10% of my charge in one hour or even less...while not doing literally anything with my screen off. So yeah, maybe it's gonna be time for another replacement in a few months
By the way I tried Greenify today. The drain was far worse than when I didn't have it installed lol. Android Marshmallow is finally that one guy who's capable of handling himself alone without helpers like Greenify so try without it, it eats up your CPU anyway (as minimal as it can be, it still does).
With 3G always enabled I can get between 3 and 4 hours of screen on time (no games ofcourse) and around, idk, 10 hours total time until it hits below 10% and asks for some juice.
This^ was simply impossible with android 4.4.2 on the same phone so 6.0.1 really impressed me a lot as I had awful memories of Lollipop (that's why I didn't update for so long actually).
To sum up: try all the software ways of extending your battery life - with/without Greenify, uninstall/disable/optimise certain apps like Facebook and Spotify (says they slow down my phone), change ROMs, change kernels, change settings and if nothing works get a new battery.
PS: When Samsung go back on track and put a removable battery + all old features in a new flagship, I'm switching to that (S9, S10, SX, whatever xd). Newer phones got water cooling (~30 degrees while gaming, S5 gets 36-40C).

Thank you very much for your long answer. Honestly I don't trust too much battery savers. I've tried in the past many of them with no visible results. In fact greenify has never shown me any benefit. Notwithstanding, in this specific case, I've seen that hibernating "mi fit" (from xiaomi) I can appreciate a considerable improvement (5-10% of gain). I own a mi band and apart from keeping Bluetooth on (which seems not to be a big drainer) mi fit abuses of this connection. In fact "tools & mi band" seems to be more energy efficient with the connection to the mi band.
In any case I'll order a new one as it is not normal to have the drain for 100 to 90 being off and idle

I've changed old battery for a new one and I haven't seen any considerable improvement. After it, I've done a factory reset and a battery calibration (using the app on the store that requires root) and nothing... Any suggestion? I have the feeling that new battery is OK but somehow my phone is unable to take advantage of its performance...

Ive just unplugged it 50 minutes ago and I have 10 percent left with only 10 minutes screen off... There is something wrong and I don't think the two batteries (old and new) are in bad state in the same way... There may be something else..

Have you tried to install the stock firmware through odin? PS: Read the instruction before trying it!!!

Right now I have DreamUX V2 A7 (2017). I flashed one week ago hoping to remove this strange battery behavior. But it remains. Do you think reflashing stock firmware will fix it? I'll check instructions before going ahead. Thanks to both!

If it gets fixed after firmware reinstall then it's a software bug. If it gets fixed after changing the battery then it's a hardware bug. If it doesn't get fixed after trying both things then it's black magic :s
Also try to clear dalvik-cache and cache and do factory reset before and after flashing.

OK I'll go ahead with this. Good guide to reflash stock rom?
I'll do several factory resets to see if it helps, but I start to think that it's black magic
Thanks

Sorry for the delay in replaying but I've made several attempts with not specially good results.
Now I'm getting 24 hours battery with 2h SOC for WhatsApp and browsing. Furthermore, I use Bluetooth for the miband.
The battery drop from 100 to 90 still remains. Maybe it's smoother but significant.
I've changed battery, changed roms (several times wiping everything). I've tried battery calibration app from rooted devices. I've tried the calibration procedure for non root devices (here I think I've obtained a little bit of improvement) but in general I have the feeling my phone is not detecting well the capacity of the battery (either new or old). Any tip? Advice?. Could it be the charging circuit? Can it be fixed? Should I keep doing calibrations more often to see if I grasp more capacity little by little?
Thanks for your time and help
