UK 1900mh battery

Hi i was in tottenham court road yesterday and came across a battery for the XDAIIs rated at 1900mh. The battery was marked on the back as being for Dopod/XDAIIs which maybe means its from the same source as O2 asia XDAIIs's but no manufacturer and came in a plain white box. Has anyone in asia come across such a battery? If i bought one could it possibly damage my XDAIIs and generally are 3rd party batteries any good? Thanks

Higher mAh has no effect on your BlueAngel, only the Voltage must mach, there a wrong Voltage can fry your Device. But as the Battery for the BlueAngel is so unique in shape, the chances are very high that it matches perfectly and is manufactured for the sole purpose as replacement Battery for the BlueAngel.

This is a very good question. And can not be answered in general. It really depends on the manufacturer. And in 99% of the cases you will hardly know if that is the truth what is printed on the battery. On German TV they show Horror-Scenarios of exploded Cell-Phone Batteries. But in my view this happens more while charging, a battery to explode while using (not using and charging) is highly unrealistic. But nothing is impossible.
3rd Party Batteries are often even better (Cell Phones, DigiCams etc) and to have 2 Batteries is the best thing you can do to a battery! Always use the battery until it is empty and then recharge it fully. So if you do that even with a "bad Battery" in mAh (=Shorter Usage Time) you will get longer Battery-Life of your original Battery. And this is unfortunately true with all Battery-Types (Although they try to tell you that LiON Batteries doe not have a Memory Effect [Same lie was told about NiMH in the beginning]) So constantly charging the Battery in the Cradle or in the Car every night is the worst thing you can do...

The exploding battery scenario is during charging,(mostly with non-oem chargers) or dropping of the phone to a hard surface. As far as battery memory is concerned,Lion batteries do not take a memory set condition as long as they are charged fully before use. Most people charge them the first time until the fully charged indicator comes on. This is wrong!!! You should always charge any battery as described in the owners manual. If it says to charge for a specific length of time, DO IT !!! Do not go by the charging indicator.If you do that, the battery will outlast most other types of batteries.

I think ill risk it and buy one tonight on my way home from work and ill post the details afterwards, i only went into one shop, price was £44.99, ill check other shops for other options. They also had the stock battery for £35, i think

I bought the battery and am charging it, ill give it an overnight charge and test it tomorrow. It fits perfectly and feels solid, difference from the stock battery is that it doesnt have an indentation and is slightly raised at the bottom but it still fits my standard case no problem. I bought it from Inkino, 020 7631 4567

which is the best battery for xda iis

hi all,
I've just bought a 2nd-hand XDA iis and is battery is not so good.
So I intend to buy a new one.
But I'm wondering which bat is the best now.
I've gone to ebay and see that they have some types: original 1500 mAh, 2400mAh, "slim" 3200 mAh and "fat" 3600mAh.
I think the 3600mAh is the most suited for my xda.
Is there any better choice? Where could I buy it?
With the 3600mAh, how long would the xda would last if I use wifi IE with the lowest backlight?
Do any of you have any problems with it?
Could I use my old charger or Do I have to buy a bigger one?
Could I still use my usb-cable (not cradle) for charging my xda?
And is there any conflict with WM5? (I've just read in our forum that someone have problems with WM6).
Thank all of you so much.

I would say that primarly it would depend on if a 'fatter' and heavier phone bothers you.
Keep in mind that just about all the cases and various accessories that hold or clip on to the phone are designed for a phone that has the original battery, so a thicker battery may well make them unusable (cases are the primary example I would give).
How long it would last is impossible to say, as it depends on how you use the phone, what apps are on the phone, and so on. Also, 3rd party battery quality does vary. Which manufacture is the best, I can't say as I've never seen any place that reviews battery life.
I've never heard of any incompatibilities when talking about a particular version of win mobile and a certain capacity battery, and can't imagine that it's even possible.
Pick one and see what you get, then post the results here so the every one else can benefit from your experience.

At last, I've bought a fat 3600 battery and I think it's a good decision.
Now, I can use my fone for browse Internet in near 6 hour with wifi; or I could use it with 5 day stanby (how amazing).
some small problems are:
- the fone is thicker and heavier (no problem with me).
- My third party charger is a bit hotter.
- And the charging time is longer (ofcourse).

do not by batteries by ACME power. I have bought 2400mAh and feel no difference compare to standard old battery. Besides, I have troubles with bt. it turns off by its self with only this battery.

I bought a battery for my Htc Harrier about 4-5 months ago. Sorry i dont know the brand of it but its says its 3200mah and "replacement for XDAIII". The inside of the battery is kind of bloated out from the heat and looks a little dodgy but still works. Ive had a few problems with it where it powers off for no reason. When i turn it on again the battery charge looks fine.
Just a couple of days ago for the first time my phone just completely hard resetted and lost all my data. I again turned it on and the battery charge was fine. im blaming that on my battery.
I use my phone mainly for listening to music on my bluetooth headphones while im driving to school and for typing things out on my bluetooth keyboard at school. The standared battery that comes with the phone simply has not enough charge time to do all this.
With all its annoying problems i still use my battery. I just make sure i back up my most important things on my storage card. And charge it every night.
Soon im going to buy a HTC Blue Angel due to my countrys crappy plans that the Harrier comes with. Maybe i might buy the 3600mah while im at it.
So my advice is if you dont need the charge of a extended battery then stay away. Unless you are like me and need the extra battery power then beware of some stress ahead that it might give you.

1500mAh Battery for Five Bucks Shipped

I've ordered from this site in the past with favorable results. Shipping can take up to 3 weeks but it is free. This battery is for the Touch Pro 2 but should work with our phones.
http://www.dealextreme.com/details.dx/sku.35632

Super! I have ordered from them as well with positive result. Let us know how the battery performs when it comes in. Thanks for the heads up!
-------------------------------------
not sent from an iPhone

That's a killer price... and they take paypal. Thanks Hexto!
My only question is... will adding 200mAh really make a big difference?

I was thinking of ordering one of these, too, but now I'm not sure if I need to. Ever since learning that the Calendar was causing my phone not to sleep, I have been being sure to keep that process killed. Let me tell you it has made a HUGE result. I unplug my phone around 8am every day and usually by lunchtime I have a battery that is about 40%. And that is just with moderate use.
Today I unplugged it at the same time and have been streaming BT audio to my car for about 4 hours straight. Now it's 4:30pm and the battery is still at 60%! All by just killing the Calendar process.
Hopefully HTC/Google can get that software kink worked out in the next release.

I agree. Ever since I found what wasn't letting my phone sleep, my battery life has improved tremendously. Also, now that I'm using TaskPanel, all apps that I don't need open get auto-killed when my phone sleeps. That's why I was wondering if the extra 200 mAh would be worth it, even if it is only $5. Anyone have any opinion?

I always like to have an extra battery for when I go camping or travel. Doubt 200mAh will make much of a difference but at that price I'd I don't have to even think about it. Its the price of a foot long

thanks for posting - I bought two to have as extras. They will come in handy at some point!

Where could I find an extra charger for batteries only?
Thanks.

Siedio has one http://www.seidioonline.com/

I agree that having an extra battery could come in handy at times. I have to say I am a bit worried about removing the battery cover any more than absolutely necessary, though. With my Droid, the battery cover falls off at will, and I wonder how the Incredible's battery cover will hold up to being removed repeatedly.

Would this charger work?? http://www.dealextreme.com/details.dx/sku.25175

My only question is, when my Incredible explodes after installing this battery, can I claim manufacturer's defect? :~P

I'd like to know the answer to this because DealExtreme has some kick ass prices on damn near EVERYTHING!

I don't see how this would work. Contacts seem to be in wrong place. The TP2 is different than the TP, but I could be wrong, it's been known to happen...

You would need to get the base plate for the TP2 battery to charge. Same as incredible.
Or you can do what I just did and placed 20 orders for my client for their incredible
Ebay hkcyberport
http://cgi.ebay.com/ws/eBayISAPI.dl...Category=20336&_trkparms=algo=LVI&its=I&otn=1
It comes with an OEM HTC TP2 battery and charger with the correct plate. It also has a USB(mini) plug to dual charge or plug into laptop.
$10.88 with battery and free shipping. I don't need it right away so the 7-10 days is not big deal.

yeah, it definitely appears to NOT be oem. If I had an order put in for oem and received that, I would not be happy

DX batteries are notorious for being over-rated in their capacity. Plus at that price I doubt if the batteries are protected from overdischarging...explosion would be a possibility.

You can also go to eBay and type in htc incredible battery
and there will be a bundle of 2 of those with a standalone desktop charger for the batteries for about 10-15 shipped.
You can also buy a 14piece bundle with screen protectors, styluses, chargers, the above battery bundle, and a couple cases and more for about 35-40$ shipped.

Well, I just received the battery from DealExtreme. Although it fits in the slot, it will not charge or power up. Either I received a DOA battery, or it does not work. Either way, save your $5.

Battery to 100% - Required Parts

First post here, be easy on me. I love this Nexus S, my first android phone, but man this battery issue has really bothered me. I would wake up in the morning, take my phone off the charger and immediately be at 96%. After 15 minutes of checking emails and surfing, I would be below 90% by the time I got to work an hour later. I was spending half the day charging my battery, so I decided to order 2 OEM batteries and a wall charger off Ebay.
Well little I did I know that this would solve two problems. First, the wall charger charges the batteries to 100% and provides significantly more life. For some reason the phone does not let the battery truly get to 100%. Second, when I get home from work or wherever, I can just pop in another battery and be fully charged again. Now I don't have to sit and worry about charging my battery all the dang time, and my batteries are lasting much longer to boot using the wall charger. I am not sure I can post links yet, so what I ordered was an M9P wall charger for like $10 and a couple extra OEM batteries for $10/per on Ebay. I ordered from US sellers so I didnt have to wait weeks also. You might be able to find cheaper if you order from a hong kong seller. Anyway, I hope this helps someone as frustrated as me.

No trickle charge is applied because lithium-ion is unable to absorb overcharge. A continuous trickle charge above 4.05V/cell would causes plating of metallic lithium that could lead to instabilities and compromise safety. Instead, a brief topping charge is provided to compensate for the small self-discharge the battery and its protective circuit consume. … Typically, the charge kicks in when the open terminal voltage drops to 4.05V/cell and turns off at a high 4.20V/cell.
There is a whole lot more info on that site, but I’ll sum up the excerpt, if you continually charge a Lithium Ion battery, it will degrade, and worst case explode, but hey, at least it looks cool when it does.
Just don’t end up like others have, for example, a Chinese man who took his phone off the charger, put it in his pocket, and then it exploded. To read a little more about that, check out EnGadget, if you want to see the phone, Tech-Ex. Here’s another one, no one was killed, but it burst into flames, over on PCWorld.

IMO. I rather have it sit at 95% than to have my phone catch on fire. Better safe than sorry.

I've been charging my mobile devices to 100% for years with no issues. I'm not too worried about it since I don't mod my phone. All I wanted to do was have a battery that lasts and I now have that. Thank you.

From what I am seeing and how much longer my battery is lasting, I am getting a fuller charge and WAY longer battery life charging batteries in the wall charger. I had the same issue as many others with this phone. The battery wouldn't charge to 100% and general battery life is pretty poor. I thought my phone was bad so I exchanged it and the battery life was identical.
I recommend everyone who questions my results, if you have a spare $20 and are sick of the poor battery performance of this phone to get a wall charger and spare OEM battery off Ebay or wherever. Theories are nice and everyone has one but I'll take real world results over theories any day.

"WAY longer battery life"? Really really? I'm having some trouble believing this. The standard battery is 1500mAh. Are the extra batteries the same capacity? Because we are talking about something around 4-6% more power here.
This is either confirmation bias or blatant advertising.
Edit:
Fun fact: These two listings are from different sellers, but both write "Samusng" instead of "Samsung".

Obviously i'm not advertising, I am just posting my observations. My battery is lasting several hours longer than it did before under similar use. Right now I'm going on 6.5hrs of light use and I'm still at 81%. The OEM batteries I bought show the exact same part # as the one that came in the phone, but say 1440mah instead of 1500. I'm not observing any difference in how long they last compared to the original battery as today I am on the 1440 one.
I've been in the IT field for 18+ years. I know the difference between real results and 'confirmation bias'. These are real results I have experienced. You are more than welcome to share yours if you choose to spend $20 and duplicate what I did.

I don't believe that unless your wonder-charger is literally cooking the batteries to death by some serious over-charging.

So, the original battery to 1500mAh, charged to 96% in the phone would give ... 1440mAh. And range anxiety.
But the extra batteries, charged to 100% in the wonder-charger would give ... 1440mAh. And a peaceful feeling.
Yeah, I don't really see the "WAY longer battery life" here. If those 4-6% extra charge gives "several hours longer" then a full charge would be good for a couple of days of use anyway. And yet you were "spending half the day charging your battery". There's something odd about your story. The numbers don't really add up.

No thanks. I have that exact same charger, and an extra original battery. If that charger actually makes that much of a difference, I don't want to cook my spare battery to death with it.
But feel free to back your claims by some real numbers taken from, you know, objective tests. One battery charged in the phone, the other in the wonder-charger. Then do the exact same thing (play music or whatever) until the batteries hit 15% remaining. Then post the elapsed times here.

Your condescending tone isn't worth my breath. My results are my results and I wished to share them with other people having battery issues and what I did to resolve them. I will continue 'cooking' my $10 batteries to a full charge and having a phone last several hours longer than it did before I started 'cooking'. You can do whatever with yours. Good luck to ya buddy.

You know this isn't your blog or twitter feed to promote what you're doing.
Just like what you said, you're new to XDA so I wouldn't be too fond on trusting you either because you haven't been around too long.
I'll continue to stick to my battery. Grats on your long battery.

I go a full day with heavy use on my stock battery. Not sure what your problem is. Unless you can put up some real numbers though, this thread is not worth anyone's time.

After ordering both an OEM battery and the M9P charger I can confirm this.
I don't have screenshots yet, but The stock battery and the replacement OEM batteries I ordered. Function at around 4-6 hours more on the wall charger. With the stock charger charging my stock battery, I was seeing around 16-19hours with heavy use(phone and phone+bluetooth/text/web/youtube) with the M9P charger charging the battery, I have seen roughly a 4-6 hour improvement in battery life depending upon the usage change(i.e if i'm playing angry bird or NFS Shift along with other normal stuff)
I am, however, convinced the pulse charging vs. trickle charging done by the stock charger won't shorten the battery life. Plating will be come a real problem later on down the line, but with any smartphone, I don't expect to keep a battery longer than a year with my use before i either replace the phone or the battery.
If you guys want battery history shots, or whatever you might need to to help you get a better picture of what's going on, please let me know. I'd be happy to provide them.

Thanks for confirming my results. I was very displeased with the battery life of this phone, but since I went to the wall charger and just swapping batteries, I am getting a full 24hrs use and still have 10-20% left when I swap before work every morning. All in all a pretty cheap investment for the gains.
I am not seeing any noticeable difference between the 1440mah and 1500mah batteries either.

Just wanted to post my experience about battery life. It lasts almost two days (I switch off my phone for six hours every night). It wouldn't charge more than 95-96% every time. And it took really long time to charge too, with the oem charger. And then I tried my wife's Nokia charger, which is also 5V output but 1200mA instead of 700mA the oem is. And charged it turned on. And there it was! A bit less charging time, and for the first time it said 100% charged. That happened the last 6 charges with the Nokia charger. I hope I am not damaging the battery with what I'm doing. I can't say it lasts more than before. Nothing noticable. But at least it's fully charged and it doesn't take all day to charge.

i get 100% everytime when i unplug it will either drop to 97% or to 96% but will still last a whole day of use. i dont charge my battery unless it turns red with the X or till it shuts itself off.

Upgrading the internal battery

I'm curious if anyone on here has tried opening their phone up to swap the battery with an upgraded mAh cell? There are 4,220mAh upgrade batteries all over eBay and I'm really about to pull the trigger on one of them. If it fits and works properly, that is a pretty substantial upgrade in screen on time daily and the difference between me having to charge one to two times in the middle of the day versus being able to go the whole day on the initial charge.

Just cause the listing and label on the battery says a capacity doesn't mean that's true. I wouldn't risk putting in a 3rd party battery that costs $20 (for example) into a $600+ phone

Well I mean that's a given with anything you buy on the internet without seeing it first. As for the price of it, a genuine OEM Pixel 4 battery is $25-$30 so I'm not put off by the $10 difference in price. I also am not going to be relying on the battery if I try it, as in if it turns out to be a dud I would just immediately swap back in the OEM battery and take the little $20 hit but I think its Worth trying with the current risk to benefit comparison and if it ends up being truthful, even if it's not 4220mAh but more than the OEM 3700mAh it would be a win in my book for the price. I have an inline USB meter I can throw between the charger and phone to measure how many milliamp hours the battery actually took.

If you need to upgrade battery to get more screen time each day then you're using your phone too much lol

After my experiences with purchasing piss poor quality aftermarket batteries off Ebay and elsewhere (N6P), I would not recommend it. For the same price you can buy a PD power bank that will fast charge your device anywhere you don't have a charger handy. That and you won't break the back glass. Of course, it would be a totally different story if your battery has somehow degraded tremendously and is now defective. I'd be curious to know what your current battery capacity is using Accubattery. When I bought my P4XL, it was 103%. 6 months later it was 98%. If your battery capacity is still 90-95% I would look at a decent PD power bank and not crack the case open. Even if you pay someone to do the work and get a warranty, your phone will never be the same. Best of luck. :good:

I would think that a battery that's 500mah bigger might not be able to fit in the phone... Chances are that the battery will just be a low quality replacement.

According to accubattery I currently have 12 hours and 25 minutes of screen on time. I dont know about anyone else but that is really good in my book and more than enough. My battery is reading 103% capacity.
I never fast charge my phone unless I forget to charge it overnight and I am leaving the house soon then I throw it on the original charger. And I almost never charge past 80%. I actually use a device called chargie that slow charges my phone overnight. It completely shuts down the charger at 80 allows the phone to discharge to 76 and kicks back on and goes back to 80. My battery only goes up about 10 degrees F while charging. And I have it set to shut off the charger if my battery reaches 110 degrees F. I really plan on keeping this phone for at least 3 years (since I have a family and I have to be a big boy and put food on the table now) No more getting the newest phone for me every year.

Well, considering my phone is used for all traditional purposes (YouTube, social media, email, web browsing) along with the fact that I run my business from my phone, you wouldn't be wrong, but it is essential and serves it's purpose. Any extra sot I can get is a huge plus for me.

Yeah I feel what you're saying, the one reason I haven't already dove right in and tried is the splitting the case open. I have don't it once before on a P4, my last one had some issues and I was able to open it up before sending it back to Google to be RMA'd.
I do in fact have a 10,000mAh PD power bank, I bought it within the first week of upgrading from my P2 to my P4. It works fine and is a great solution but obviously being able to fix the root problem would be better if possible. The power bank is along the lines of a bandaid for the problem but seems to be my only logical choice for now.

12 hours screen on time? What alternate plane of existence do you get that kind of SOT with a P4XL??

I just opened up mine the other day to replace the rear glass ( had a crack in the corner). Was pretty easy with the guitar pick looking spudger. I did not need any heat to open it. Figured while I was in there might as well replace the battery with a fresh one. Both were purchased from ifixit. The swap out went fairly quick, I just took my time to scrape all the sealant from the edges of the phone for the back glass to have a good seal. Haven't dunked it yet to test if its still waterproof.

No I actually never ended up pulling the trigger on it. To be honest, I'm still really interested in the idea. The only slight bit of anxiety it gives me is with breaking the factory adhesive on the rear panel. Still, I will try it soon. I hate having to dedicate a pocket to my power bank anytime I'm out for more than a couple of hours.

What adhesive did you replace the factory stuff with and where did you get it?

The 3 pull strips for the battery didn't fully come off so there was still some that I could reuse to secure the battery. The rear glass that comes from ifixit has everything (nfc,qi, camera lens gasket etc) already attached to it including the adhesive. They also sell just the adhesive strip by itself if you're just opening it up.
