[Q] My Desire Z isn't responding to the charger! HELP?

Hello everyone, yesterday, my two months old HTC Desire Z (NL, no simlock, CWM 3.0.0.5, CM7RC2) ran out of battery. When I put my phone back in the charger later at night, the red LED began flashing, 2 flashes (interval about 1sec.) and than no flashing for 2 or 3 sec. and starting over again. it sometimes boots into recovery, but then turns itself of after a couple of seconds. I left it in the charger a full night with no effects, let it "rest" for about 8 hours and put it back, still no success.. Anybody an idea? thanks in advance ;-)!

Did you try a battery pull? Leave it out for about ten minutes.

I was just going to put it back in after half an hour.. will edit if something happens, don't expect it as nothing happened after all the things I already tried
EDIT: goes flashing again, let me try to turn it on.
nope, nothing : (

This may seem a bit obvious, but did you try charging it through your computer? The AC adapter could just be broken.

That's not it, in the computer it doesn't even do the flashy thing. I think it's the battery, i'm going to buy a new one soon, €30 -.-" but since my warranty's gone it's worth the shot. keep coming with ideas please though! : )

Li ion batteries will stop taking a charge if they are over-discharged. Li ion batteries have a safety circuit that is SUPPOSED to prevent over discharge, but they don't always work. I've seen this happen to several folks over on the Touch Pro 2 forums. Charging overnight on the wall charger will sometimes work (USB is not enough). Otherwise you need a special charger/battery tester with a boost function to bring the battery back from the dead. Short of that, you just need to get a new battery.
Its possible you may have some issue besides over-discharge, such as a bad battery. But just in case, in the future it would be advisable to avoid discharging the battery below 20%, or at least 10%, whenever possible. Some here have claimed that newer phones, or perhaps the Android OS itself is better at preventing over-discharge of the battery. But this is the second post I've seen on the Vision forum with this same problem. So my inclination is still to be as cautious as possible with draining the battery too low.

I had this same issue once before, let my battery run out and then it wouldn't charge or turn on, so like stated above, I had a travel wall charger from chichitech and put the battery in that over night and it brought it back.

Honestly: I'm from the usa, I don't even know what the desire is. I'm assuming its a non us version of the g2.
In the tmobile store there are bigger batteries u can buy, I got the stock battery and never upgraded but I did see them there..
Go into your local store and I'm sure u could test it right there with there batterys.. if u don't wanna wait for ur friend that is..

I've been using the red chichitech 1800mah EVO batteries since October and love them, you just have to peel the red wrapper off and they will fit under the stock door. Plus for the price you get two batteries and a wall travel charger for what one stock battery will cost you, look for Chichitech on Amazon, I got them three days after I placed my order.

There is an Asian Desire Z too. In fact, the Desire Z is so much more widely distributed, I'd dare say the more definitive version is the Desire Z, and the G2 just happens to be T-Mob's variant. But that's just me. They are all Visions in the end, aren't they?

Battery Differences btw HW versions

I'll ask my question up front - has anyone found any discernible differences in the batteries between HW versions of the EVO, specifically between HW0004 and HW0003?
To make a short story long:
I bought my first EVO back in december from a guy on craigslist - he met me at a local sprint store, verified the ESN et al., and he basically told me he was getting rid of it in order to switch to the Epic. He said he'd had one EVO, it broke, and he got another one. I'm assuming the one I got from him was the second one, which looked refurbished (only in that the battery had some scratches on the sides). That EVO was HW0003. I primarily ran myn's Warm RLS 5 on it with netarchy/toastmod kernel (havs-more-sbc for anyone interested), got seemingly great battery life for how much I used it.
Back at the beginning of June, that phone went for a swim in the local lake. I retrieved it, and luckily I had sprint's TEP. Got a replacement overnight, but sent the old dead phone back and kept its battery. The new phone which I now have is HW0004 - was sent to me new in retail packaging. I have followed all of the same battery saving 'tricks' I've read on these forums and elsewhere, but the new phone with the new battery didn't seem to last nearly as long per charge, especially on Warm RLS5 with the same kernel as before. Yesterday, I decided to try an experiment - since I still had the old battery (even though it ostensibly has water damage), popped it into the new phone instead, and after fully charging it noticeably increased overall battery life. I'm running the Synergy RC1 ROM now, so I haven't compared with Warm RLS5 directly yet, but this indicates to me that there are differences in the batteries beyond just slight, circumstantial manufacturing differences.
Has anyone else noticed this or anything like it? I'll keep this thread posted with what I find once I flash back to Warm RLS5.

I can tell you from experience there are definitely differences. The original battery I got with my 003 EVO was the best. A friend that works at a Sprint store grabbed a couple more. One looked pretty much like the original and was roughly on part but the second one didn't look the same. The first two were black with the red label the second was wrapped differently and had silver showing. It was still an HTC battery but no where near the capacity of the other two. Pretty much like a cheap aftermarket battery. Hope that helps.

both of these batteries show silver and are wrapped exactly the same - couldn't tell one from the other if it weren't for the scratches that have always been on the older (refurb?) battery and the water damage indicator being filled in now. What you're describing sounds like a possible change in third-party manufacturer of the batteries. Interesting though...

[Q] Cannot connect to 4g when using HTC 2750mah battery and cover

I purchased the Thunderbolt about 3 weeks ago when in vegas, along with the HTC 2750 mah Extended Battery and door. That phone had on and off trouble connecting to the internet and all I used was the extended battery. Eventually thanks to the seidio holster my original Thunderbolt fell to the ground and screen cracked. I now have a brand new (I think) Thunderbolt from Asurian and I am home in North Jersey. When using the original stock battery with the device 4g internet works fine. When using the HTC 2750mah extended battery I can only connect to 3g. Choosing just LTE mode connects the device to 1x, and choosing full auto mode connects the device to 3g. My extended battery cover has the 2 spots where the antennas are. So I do not know what is causing this problem. When asurian sent me the replacement phone it included all new parts, including new sim card, if that matters. I have not rooted or done anything yet to the phone. Complete stock experience.

it may be that the antenna contacts on the extended battery cover may not be making contact with the antenna points causing you the 4g problems. I'd double check that.

Sounds like a bad battery cover.

Update: I have 3 different extended battery door covers all with the antenna contacts. None of them work with 4G. Standard battery and cover work fine still. Is there something on the contact points I need to remove?

I would just head into a vzw store and have them mess with it

lost 4g

I think the problem is more serious then that. I just received my htc extended, and have the same problem. Before had 4G with standard battery, but now 1x with the extended.
Unless I find a solution I will return the battery in a couple days.

At one point when they first came out with extended battery there was a batch of them that had antenna problems. But I remember they recalled them
Wonder if the same trouble is back in the store they can put the bad covers on a different thunderbolt and see if it has 4G problems if it does you need a new cover.
Thanks,
Bryan

Def a bad cover. The cover has antennas on it so if they aren't making contact properly you will not get proper signal.

[Q] Anyone know of other phone batteries that work in E4GT?

My battery is completely dead and is swollen to the point where I cant even get back cover on. I was looking to pick one up locally and I live in Chicago and thought it would be pretty easy to find replacement. Its not at all. Even the Sprint stores say they are all out of stock for replacement batteries for the E4T they only have the extended ones for 100bucks. I really dont want to be out of a phone a the few days that it will take to ship. Are there other phone batteries that work in a E4GT that may be more common that someplace like best by will have in store. Thanks

The OG epic....make sure u return that battery to Samsung and make them send you a new one. It may take 3 weeks, but your gonna need that

Just came across same problem in Orlando. 2 sprint stores, 2 batteries plus, 2 radio shacks, and one best buy. Nobody has our battery. Batteries plus could order it for me, and it'd cost $45. I ordered 2, plus an external charger off amazon, paid for overnight shipping, total cost $33. Regular shipping total was $14 I think.

Order on Amazon. I don't know if best buy carriers them in store but the do carry an extended battery and radio Shack has the same one as best buy. Check stock at stores around you. Or take it to your service provider, I think Sprint might switch it out. You can get the one from best buy or Radio Shack for like $25.

Cool, a sprint store gave me a battery even though I was out of warranty. Actually they didnt even see my phone. I pulled out the battery and showed them it was about to explode. She grabbed it took it in the back and brought out a new one. Its a 1500mah but she said to come see her tomorrow and shed give me the 1800. Very nice of her.

Also guys don't forget ATT and T-Mobile have Galaxy S2 in case something like this comes up again. Lots of swollen batteries lately.

Any sgs1/sgs2 battery will fit but sgs1 batteries are only 1500mah instead of 1800. You can find pairs with external chargers for about $25 on Amazon, Hyperion, anker and empire are the best non OEM brands. I'm actually going to sprint tomorrow to get mine replaced if they have any in stock around here, and then once I get a replacement I'm gonna order a pair with charger off of amazon so I have 3 i can rotate to help prevent the bulge reoccurring. Mines not super bulged but once it drops below 40% it will flicker and shut off and when i reboot its dead until I plug in and reboot then it jumps back to 40%+. Its quite annoying

The t-mobile sgs2 battery doesn't fit. It's taller.

[Q] Will The Door Fit?

Thursday i bought a 3800mAh extended battery from ebay with sprint in the title and also on the battery itself from the pictures i saw. I looked in the description and it also said verizon in it and was a tad confused as to will it fit. For $15 i figured i might as well try it out and see but it gets here monday. I just wanted to know if anyone knows if it will fit on my sprint galaxy nexus properly? or maybe i will have to make some alterations as long as it works? link for it is: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370639867086

Cant say for sure but the teeth that hold it in place are supposedly in different places.

I read that one or two may be out of place but all of them?

Even one or two would ruin how it's seated on the phone.
The guys in the accessories section probably have a better idea of it.

Well the battery came today and had 53 percent left on it. Currently im doing the initial first full drain and so far im already very very impressed! I can already see an increase in battery life. The door fits perfectly on both of the batteries(I ordered two of em) with no problems what so ever. Great so far. No problems with it snapping on at all

Okay im slightly confused, should i drain the battery first or charge it fully overnight?
