keep the battery in? improve the latch? - MDA III, XDA III, PDA2k, 9090 General

I've seen several posts about hard resets and problems with the battery. Has anyone come up with a solution to keep the battery on? The little latch system really sucks. I bought the v3 2400 lion battery and it occationally wiggles loose. Anybody come up with some type of mod for the latch to work better?

Verdict? Seidio 3500 mah or Sprint 2600 mah?

So what's the verdict? I've read tons of threads on these two batteries, all good things but my question is, if the Seidio 3500mah has more power, why not get that one over the sprint's 2600mah? Just makes more sense to.
from my understanding:
1) They are the same size
Only drawback from getting the Seidio would be:
1) There are reports of the back cover not completely "fitting" properly on the EVO, is this still the problem or have they fixed their back cover for a more snugged fit?
2) Sprint's battery comes with two color backing, white and black
Your impressions? What would you get?
Well one clear benefit of the Seido battery is that they also make a case that fits it. I don't know what shape the back on the Sprint model is but unless it is like the Seido you wont find a case to fit.

I can see a potential advantage to the HTC 2600mAh battery:
It's pretty apparent that the Evo has some issues charging extended batteries. There seems to be some kind of charging limit which can stop the charge cycle prematurely when you charge them in-phone. Being as the 2600mAh extended battery is an OEM aftermarket part it stands to reason that HTC might be working on a fix for that, but there's no guarantee that the same fix will work for a battery with ~35% more capacity that the OEM extended battery.
One possible scenario is the battery may talk with the phone (handshaking) via the extra contacts on the battery. That's actually pretty common with cameras and camcorders. For example, my Panasonic camcorder automatically adjusts the "Time Remaining" display when I put a larger Panasonic battery pack on it but the display doesn't even work when I use a brand-X pack.
But the truth of the matter is there is no guarantee that HTC is even working on a fix for it's own extended battery and if that's the case, the extra 35% capacity and the fact that Seidio offers cases and other accessories which support their extended battery gives the advantage to the 3500mAh battery.
However: batteryboss.org reports that the 3500mAh Seidio battery actually has only 2821mAh of usable capacity which is only 81% of the published capacity. Unfortunately there is no like & kind data on the HTC battery to compare that to.

as far as the back cover goes on the Seidio, it fits VERY tight.... this suprises me because it came with one of the tabs broken. (i superglued it back on, who knows if it will stay?)
It lasts me all day long so far, I have been trying to run it down so I can get a full charge at night. I know that conditioning is not "required" with these types batteries, but I still like to do it anyway.
It does seem to drop to around 70% rather quickly, but the lower the battery gets, it seems the longer it takes to display a lower percentage.
I had both but stayed with the seidio only cause they had a case for it , I got the shell case just covers the back and sides , but as for battery life am only getting 2hrs more than the sprint of course with my type of usage which is heavy.. so there both good just depends if you want a case now or wait till sprint releases cases for theres...
I have the seidio battery, which has a back cover that fits pretty snug, despite coming with one broken clip.
The battery capacity is confusing. I charge it until the light turns green, with the phone on. It will drop 20-30% really fast, then decreases slowly.
If I charge it until the light turns green, then turn it off and plug it in, it will charge more until the light turns green again. As soon as I turn it on, it drops to 96% by the time the phone starts up.
I plan to keep doing this, as I had a simillar problem with an HTC Mogul, however that phone would just freeze at the 80% threshold, and each time I did it raised that threshold to a higher percentage before it would crash. I know this phone is not crashing, but I wonder if there is some OS level driver or setting that needs to be adjusted or hacked? If there is, I have NO clue how to do this.

Mugen 3200mah Battery Review

I'm gonna start off short with this and add more as I get more use out of the phone.
First of all, I was hoping (though not optimistically) that I could fit this battery inside my phone case if I left off the battery door. This is definitely not going to happen. I've read that this battery and replacement door increases the phone from 11mm thick to 17mm. I've measured and verified this, but holding the phone in your hand it seems like about double the original thickness. Really this doesn't bother me except I'm going to have to modify a case to fit now.
Also the battery door that came with it is plastic. I was concerned this might affect reception since the OEM door is reported to be part of the antenna system, maybe for WiFi. but so far I have noticed no problem at all. I'm still concerned the tabs will break of of this door easily if dropped since they are plastic. I also am a little concerned these could break in my jeans pocket when I'm squatting down since extra thickness puts more pressure on the phone.
Initial impressions of battery life are fantastic. It had gotten to the point where my phone would die between 2-4pm after charging all night and using it pretty heavily during the day. If I tried to watch a movie around even 10am, the battery would die before the movie finished. This morning I watched a 2hr movie with the Mugen battery and still had over 80% battery left. Amazing. It's such a startling difference that I now wonder if my OEM batter was worn out more than I had thought.
A couple of final details. The buttons on the side of the phone are just slightly harder to find with the new battery door. This is not any issue after getting used to it but just an observation. The fit and finish of the battery door is very good. I did notice a slight difference in the paint color of the battery door compared to the back of the phone, but I used to work in the paint industry. I don't think most people would notice or care.
********UPDATE*************
I had cut some slits in my Amzer case to allow it to fit the extended battery. This actually worked pretty well and had a really nice feel in hand. However, it this face fits kind of loosely to begin with and has a lot of grip, making it hard to get in and out of pocked. This problem does not really get worse, but certainly isn't any better with the bigger battery. Unless you have pretty big pockets it's just too annoying. Without the case I have no problems sliding the smooth phone in and out of my pocket and it still has a better feel in hand than the stock shape. I just hope I don't drop it.
The capacity is still excellent after a week or so. I have noticed that charge time is quite long though. A full charge is taking me around 6 hrs. This is with a aftermarket cable, but I believe it is still charging at 1A. I will use the stock cable tonight to confirm.
Added an update.
please add some pics!
and how long is it lasting with heavy / light use?
I posted some usage info already, but I get almost 2 days with light/medium use. I can still get below 10% with 18hrs of heavy use... texting, reading, a little YouTube, music, WAP, and web browsing. I used to have a dead battery by 3pm using it like that, now it lasts all day.

[Q] What's wrong with my battery? :(

Ok I've looked for a similar problem and tried to fix the issue on my own but I admit defeat and need help. Recently my battery started acting funny while charging and don't know why. I'll have it on the charger it will begin to charge and then all of a sudden my EVO 4G will disconnect and there will be a yellow triangle warning over the battery in the status bar. And if you try unplugging and plugging it back in makes no difference same thing will happen. I've tried wiping battery stats and also tried pulling the battery and reinserting it but no dice. Any help is welcome. Thank You in advance.
Time for a new battery. Are u using the oem charger?
Sent From Space Using My ICS Flavored Sensation
yes I am. Is it just a faulty battery?
Yep, I'd say your battery has passed on to the great beyond....
The warning sign over battery means the phone is not communicating with the battery properly which can mean a few things, either the terminals on the battery or phone are damaged or dirty, or the battery has started to go south it has a bad voltage regulator or bad cell
We are legion, for we are many
Ok so I guess it's time to get a new battery........that sucks
Check your terminals make sure they aren't dirty or bent if they are dirty a qtip and 91% isopropyl alcohol works wonders if bent a #1 precicion flathead is a good tool to reshape them or a pair of round nose jewelers pliers
We are legion, for we are many
Weird thing I pulled my battery, rebooted the phone and it seems to be taking charge normally again.......I'm still gonna invest in a new battery since the possibility of this happening again seems big. Any suggestions on a reliable extended battery? I've heard of gorilla something or another but not too sure............

Thank you all for the help. Nothing seems out of sorts except for the battery so I placed an order for one. Still have my old battery that the phone came with so I'll use that until the extended one gets here. Thank you once again
@theMC1192
If you dont mind me asking where did you order your battery from im looking for an extended battery.
Hey,
The first thing when you have an issue with your phone sprint tells you to take out the battery and reboot it can solve many problems! For a reliable extended I would get the Seidio, or go to sprint and get one of their extended batts they are more expensive but you are guarantied quality unlike those cheap 6 dollar ones.

Battery Mod + Solar Cell

Hello everybody, first post on XDA!
I am planning to mod my Nexus 5 battery. Considering that the dimension of the original battery is 57mm*60mm, I planned to buy 4 Sanyo 3,7V 840mAh and connecting them in parallel. I would like to post links but as a newbie I am not allowed to do so.
These are 14mm in diameter and 50mm long, meaning that 4 of them would be packed in 56mm*50mm, with 10 extra free mm where I can comfortably fit the "charging board" that I can unsolder from the old original battery. The problem here is that the charging board will probably have more than 2 pins, the others being for temperature and data. How can I deal with them? I haven't teared my battery yet, so I cannot see how the chip really looks like. Does someone know whether the data pins end up in the circuitry or are they somehow connected to the battery itself? Because in this latter case I would really have no idea how to deal with these extra pins...
In addition how will the circuitry and the phone itself deal with the increased capacity? Should I tell the phone the capacity has changed or will it auto adapt? I have read tons of posts on this topic, all saying different things...
Certainly that will increase the phone thickness and I plan on 3D printing a custom designed back-cover. Luckily the original 3D model is downloadable from GrabCAD for free, that is a good starting point. What material would you suggest me to print it in? PLA, ABS, Nylon?
Furthermore, I am planning to add a nerdy solar cell 4v, 35mA that will certainly do basically nothing except help in real emergency charging the phone while off, but it will give an awesomly nerdy look. The solar cell I am talking about is 32mm*39mm and would perfectly fit on the right of the camera.
I could fit a 100mA solar panel, or avoid the battery mod at all and just fit 5 of those solar panel for a summed max current of 175mA...
I plan charging the battery with direct connection of the solar panel to it through a diod. The only thing that worries me is that while 35mA are less than what the phone draws during standby, the battery indicator will never go crazy seing the battery tension growing while no charger is plugged in. On the other hand, higher currents, will actually be able to actively recharge the phone creating confusion to the phone that would not be able to realize what is going on. To avoid that I should connect the solar panels to the usb charging port. That would put the phone into charging mode and thus in a energy hungry more that could again cause battery to drain instead of charging or anyway to charge incredibly slow.
If someone is interested in this project and has suggestions of any kind I will appreciate and I will share the results.

Firstly I would scrape the idea of a solar cell, it's going to generate very very little power especially since its going to be pointed down. Also that 175mA is probably going to be something smaller in the real world even under ideal condition it'll be almost impossible to generate that. Now for the batteries you would like to put into your phone, you have to open up your phone or find dimensions and see how everything fits together. Sometimes their will be some space around the battery and this is put for several safety reasons, so I do not recommend filling up the space if you go ahead with this replacement. This could lead to battery overheating which could cause it to leak and cause a short and destroy your phone. At the end of the day I really wouldn't recommend anything attempt this unless you really know what you're doing and the risks involved with doing this. I don't feel the increase in battery life would offset the risk factor of attempting this. Also I should mention that when you solder that it's going to be very fine and sensitive solder work, there are many things on that board that will be heat sensitive and power sensitive so using something like a $50 Weller wouldn't be sufficient.

Battery dimensions, anyone have one lying around?

Does anyone happen to have a HTC10 battery lying around that they could measure for me?.
I'm just trying to figure out if with some slight modification to the plastic frame it would fit in the htc9. Obviously a more recently manufactured battery with an extra 100mah would be a much better option than older stock htc9 ones. Soldering the HTC9 battery connector to the 10 battery shouldnt be a problem at all if different.
Thanks.
