[Nexus One Q&A, Help & Troubleshooting] uansari1:
Look guys... the reality is that this discussion is really just academic. Take my recommendations, for example. It would be ideal if everyone could do what the study I read suggested, but it's not practicable to always top off the battery and not deep cycle the battery frequently. That being said, I'm sure the difference in battery life wouldn't be apparent for a very long time. I can't imagine phone and battery manufacturers haven't thought about this. So...while I've posted my "recommendations" based on that study... just enjoy your phones.
[Nexus One Q&A, Help & Troubleshooting] scottypimpin636:
A new battery cost <$50 i'm sure... If you left your phone plugged in over night, every night for a year it probably won't hold a charge better than someone that unplugs in once it reaches 100%..

I personally would rather not deal with always worrying about over charging it and IF i still had the phone when the battery needs to be replaced, just replace it.

In the past 16 months i've had the Touch Pro, Palm Treo Pro, BB Bold & now the N1.. so i never have a phone long enough to even care lol.
[Nexus One Q&A, Help & Troubleshooting] Paul22000:
I guess that's true. We can always replace the battery, unlike the Fruit people! :D

But I was just worried that the damage happened quickly. But I guess it's 9-12 months before seeing any real effects anyway.
[Nexus One Q&A, Help & Troubleshooting] uansari1:
Actually, it's only $25 from Google. ;)
[Nexus One Q&A, Help & Troubleshooting] Paul22000:
Link?

I don't see an accessories page at www.google.com/phone

[Edit]: lol nevermind, you have to click "Get your phone" to get accessories haha
[Nexus One Q&A, Help & Troubleshooting] uansari1:
Lol... click on the link you posted, click "Get Your Phone" and it's listed right below the Dock!
[Nexus One Q&A, Help & Troubleshooting] Paul22000:
Yeah just saw that. Kind of silly to put it there since people looking for accessories already HAVE a phone. Silly Google :D
[Nexus One Q&A, Help & Troubleshooting] Paul22000:
Oh, so by the way, this page brings up a good point:

Is there any difference in charging from USB vs AC adapter in terms of how it affects overall battery life?
[Nexus One Q&A, Help & Troubleshooting] uansari1:
Probably negligible if at all. I've heard some people say that the phone is designed to primarily be charged with the adapter, and slow charging it isn't going to improve battery life. I tend to think that HTC knows what they're doing.
[Nexus One Q&A, Help & Troubleshooting] JoshHart:
Either way its not gonna hurt your phone just your battery so i dont think its a big deal. I know for my G1 and mytouch i had a couple batteries because they were like $10 on amazon im sure nexus batteries will be also soon. Wouldnt worry too much about it, just get another battery if you notice yours slipping.
[Nexus One Q&A, Help & Troubleshooting] ap3604:
I know how you feel. I to am a recovering iPhone battery stressor ;)

The main reason I chose a Nexus One and sold my iPhone 3gs was because of the ability to change the battery once it starts going bad myself, instead of sending my phone to apple and paying them $75 to change it. I'd always be in constant fear of overcharging my battery and shortening the life of it since if it went bad I would be screwed.

Google just started selling accessory batteries on their nexus one website for $25... a huge win imo since I thought they would try to screw us and make them at least $40. So now I dont have to worry since every year I can replace the battery for a mere $25.

I know I used to be the same way thought about hurting my battery since I came from the iPhone where if you messed up the battery it would cost you dearly... I wouldn't even charge while I slept due to fear of running down the battery, I would always charge it while I was awake just to be sure. But over time you will start to relax like I did ;)
[Nexus One Q&A, Help & Troubleshooting] bobdude5:
seriously is that so wrong! ugh my friends always give me **** about switching phones so often, and then they say "why would you spend so much for just a phone" ITS NOT JUST A PHONE YOU STUPID ASSHOLES! ..im irritated
[Nexus One Q&A, Help & Troubleshooting] Makaijin:
To be honest any half decent charging circuitry has overcharging protection. It should either automatically reduce charging/draw current to trickle level (electronics), or diverts the extra current elsewhere (car alternator) such as a resistor hooked up to a heatsink. In fact all Li-ion chagers have to have an overcharging circuitry or the li-ion WILL explode if it's voltage gets too high.
[Nexus One Q&A, Help & Troubleshooting] Papichulo06:
I have noticed the bottom of my nexus getting pretty freaking hot when charging it. I understand it's suppose to cause some heat but other times, it doesn't get too hot. Is my phone just weird or is this happening to anyone else?
[Nexus One Q&A, Help & Troubleshooting] uansari1:
That's normal... it will get cooler as it approaches 100% and will feel normal when it's done charging.

[Nexus One Q&A, Help & Troubleshooting] SiNJiN76:
Not sure about that...Aren't laptop batteries Lithium Ion also? There are instructions to unplug the battery of the laptop if it's to stay plugged in for 2 weeks or more. Well, I didn't read that until it was too late. The Battery will not hold a charge. So, I'm guessing that the Lithium Ion in the nexus is similar...But, of course it's obvious that it highly unlikely for anyone to keep their phone charged in for over 24 hours?
[Nexus One Q&A, Help & Troubleshooting] Paul22000:
How long did you leave it plugged in?

And how old is the battery?
[Nexus One Q&A, Help & Troubleshooting] sthoeft:
I strongly aggree with uansari1. He is absolutely right with the battery.

Remember, we are dealing with LiIo (or LiPo) batterys not any crap like NiMh or NiCd or Pb batterys. This batterys do have absolutely no memery effect. All you have to do is calibrating the software of your device (phone, notebook, etc) so that it knows where to marks as full and where to mark it empty.

It doesn't matter wether you leave your phone at the charger or not. Overcharging will kill the battery of our beloved N1, but I think and hope that Google and HTC where smart enough to stop charging when full (like every device does, even a good RC charger). So leaving it at the power won't do any harm.

Letting the battery get down to 0% will kill it, or at least will make it loosing a lot of power (20% or so) with just one event. But, when your phone switches off it won't be at 0%, it'll be somewhere around 10%, just don't switch it on again to send the last SMS or so. If you don't believe me that look for a discharging tool (there had been some on Win Mobile) and look how many mAmp has been gone when your phone says good bye.

Lifetime of a LiPo or LiIo battery it determined by two factors: temperature and charging cycles. OK, we have no way to change the climate we are living in, so lets live with it (jet there are a few extrems where you can have impact on temperature: don't let your N1 lay on top of a heater, don't play havy duty games while connected to the charger, when navigation + mp3 run in your car think about needing of a power cord). A charging cycle is one charging from 0 to 100%, so charging from 90 to 100% is one tenth of a charging cycle, or charging from 99 to 100% is, guess, one hundert part of a charging cycle.

So, where does this leave us? LiPo batterys are very user friendly and forgive a lot. Plug it in while at home or at work (if you can) no matter how many percent battery is left. The worst what can happen is that your N1 runs flat, switches off and you have no chance of getting it to a power source in short time (means a few hours) and risking it really runs down to 0%. This is the point your batterys says hello to nirvana (a least a big part of it).

So, there will be a few out there who think I'm talking bulls..t. For them: I know what I'm talking about. I'm since a long time into RC-controlled models (Ships, Cars, Planes and Helicopters). I'm working with batterys since I'm a child of 10 years (now I'm 32) and met all the types mentioned above. Thatfor I know what I'm talking about, I don't what to spend 80-120 € each time I want to fly my helicopter because I killed it's LiPo battery. You need a decent charger and a good electric to prevent running the battery flat or overcharging them (in time or charging power) or to loose calibration of the different cells. On the last two points we have no influence with our phone chargers, we have to hope that HTC did do a good job (what I belive they did). The first point is fully in our hands.

Excuse my spelling and english, I'm not a native speaker (German)
[Nexus One Q&A, Help & Troubleshooting] Ok_Kaleidoscope5109:
sthoeft brings up a lot of good points.

I suppose someone needs to investigate whether trickle charging is an issue. If you can verify it's not, then that's fine.

Many people remove batteries for FEAR of trickle charging. Most laptops don't charge till you hit 95%. That's well over a week or so on my MacBook Pro. Then it'll quick charge back up to 99%, and slowly deteriorate. I don't mind that. But if it's constantly trying to hit 99.9%, then you're going to have some major issues with battery longevity.

My guess is since my Droid doesn't trickle charge the N1 doesn't either. Are you better off running 100% => 33% and then charging every 2 days? Probably. Don't run your Li-Po battery to 0 though. That's bad. But you MAY need to do this every 3 - 6 months to calibrate the battery. Apple suggests this with their Macs, and it's a concept well known in the battery industry. You can probably just skip this unless you feel your battery indicators are really off target....
[Nexus One Q&A, Help & Troubleshooting] SiNJiN76:
It was plugged in for maybe 6 months or more...laptop became a desktop. It happened about 1 1/2 years ago...I'm gonna guess it was in use for about 6 months...before my 'Doh!' moment.

"At a 100% charge level, a typical Li-ion laptop battery that is full most of the time at 25 °C or 77 °F will irreversibly lose approximately 20% capacity per year. However, a battery in a poorly ventilated laptop may be subject to a prolonged exposure to much higher temperatures, which will shorten its life. Different storage temperatures produce different loss results: 6% loss at 0 °C (32 °F), 20% at 25 °C (77 °F), and 35% at 40 °C (104 °F). When stored at 40%–60% charge level, the capacity loss is reduced to 2%, 4%, 15% at 0, 25 and 40 degrees Celsius respectively." - Wiki -
[Nexus One Q&A, Help & Troubleshooting] gregnotcraig:
My family was always interested to see my latest phone, received as part of my membership in "Phone of The Month Club" :D

Though I think I'm with the Nexus for a time.
[Nexus One Q&A, Help & Troubleshooting] lolobabes:
using while charging causes most phone batteries to be hotter than usual... based on my humble experience....
[Nexus One Q&A, Help & Troubleshooting] bruisah:
sthoeft is pretty close to the mark on this one. It's not entirely accurate to say that LiIon/LiPolymer batteries have absolutely no memory effect - they do, but it is very subtle and is not really a significant factor in the deterioration of the performance of a battery.

As he stated, the two main factors affecting performance are charge cycles and temperature.

Bear in mind what a battery is; a set of chemicals designed to store and release charge - there is a continual energy conversion going on between chemical storage and release.

Over time, regardless of how you treat your battery, chemicals will break down into more stable states - unfortunately, this includes states that are less 'free' to store or release electrical energy.

This break down process will increase according to high or low temperatures, charging cycles, and charge storage (or lack thereof) - think "wear and tear".

There is a very good article at batteryuniversity (search for "How to prolong lithium-based batteries" in google and you'll find it - I'm too new here so I can't post external links <sigh>) that has more detail.

Finally, as for actually using a battery - as has been stated several times, charging circuits are very good these days at protecting batteries from various potential [sic] disasters like overcharging, over-voltage, etc.

As long as your device doesn't get hot, might as well leave the battery topped up. After all, your phone won't be much use if it falls flat and you're no where near a power socket!

As an aside, it's worth commenting that my work laptop (less than two years old) has a battery life (now) of about twenty minutes. Originally, it would go for two hours, easily. The cause? I have the thing docked all the time, and the battery plugged in. The laptop gets pretty hot (just feel the underside and it must be > 40C). So the battery has been slowly cooked.

It's a work laptop, and I rarely need it to run on batteries, so I have been a little lax on that front, but serves as a real life demonstration of how a modern Lithium Polymer battery will still deteriorate despite claims of 'no memory effect' etc.

:-)

Bruisah
[Nexus One Q&A, Help & Troubleshooting] maedox:
I agree with Bruisah. Leaving your phone connected to power all the time degrades the battery fast(er). Like he said about his laptop... I have warned people about that at work since forever, and still they complain when their batteries die after two months.

My "old" HTC Magic still has a very good battery. I can honestly not see a degradation in standby time compared to when it was new some time in the summer last year. I unplug the charger when it is full as soon as I notice it is at 100 %. It doesn't hurt to leave it on for a while once in a while. I charge it up again when it's at 50 - 60 %. Sometimes lower or higher, just to change the pattern a bit from time to time.

There is some fairly advanced electronics in batteries these days, but I wouldn't trust that to keep it performing as new for a year if you keep your phone on the charger all the time.
[Nexus One Q&A, Help & Troubleshooting] gunnner:
Well, that explains why my MacBook Pro's battery died prematurely. They replaced an overheating logic board, but only after it must have killed the battery.

What's all this about the battery needing to reach 4.2V for several hours to fully charge? My battery life isn't great. It looks like it's being charged to 4.17V overnight and sitting there - is that close enough?
[Nexus One Q&A, Help & Troubleshooting] McFroger3:
I have never has an issue with any batterys leaving them plugged in. I always leave my phones plugged in when im at home and not using it. Not one phone I had has had any issues with the battery degrading.
[Nexus One Q&A, Help & Troubleshooting] liam.lah:
I was going to create a thread on how to look after your battery, but there are a lot of cluey people on here who have made come crucial points, so i will finish by posting where i got most of my information from, it is the same one mentioned by bruisah

This is a nearly definitive guide to getting the most out of your Li Ion battery.
[Windows Mobile Development and Hacking General] Diagrafeas:
I am using Visual Kitchen to build my ROMs. There are five types of files that are used to eventually create the registry: *.hv *.rgu *.reg *.provxml *.xml. I'm trying to find a program that takes all these files one by one and create ONE *.rgu file. When adding keys to the One.rgu the program should check whether the key exists with different value and ask the user whick value to keep. Is there a program like that? Could someone make one? I am not a programmer myself so i can't do it but i believe that this would be very useful for all cooks.
[HD2 General] geekyhawkes:
I have seen that the new release of microsoft marketplace allows install onto the SD card (finally!) The next obvious question is how do i get this onto my leo? I have looked on the version i have installed but cant find an update option anywhere.

Thanks
[HD2 General] EddyOS:
when you sign in it usually asks to check for newer versions
[HD2 General] mndl632:
it should update automatically when you start it up, the option to choose where it installs is in the settings, at the top it should allow you to select the default install location
[HD2 General] ozkaya:
for me, it wasn't auto updating, so I uninstalled marketplace from programs, then clicked the shortcut in Start Menu and it downloaded the new version.
[HD2 General] geekyhawkes:
Thanks, i had to remove and then use the shortcut to reinstall.
[JAMin, XDA Neo, S200 Software Upgrading] cscheng:
This morning I tried to flash bikertibi's WM6.5 ROM.

In the middle of flashing, the connection was lost and now my phone is stuck in the tricolor bootloader screen.

the weird thing is that the screen keeps flashing? is like it keeps restarting every 15 seconds or so. So it can't retain a connection with my computer long enough for me to do anything.

when i take out the battery and leave it for a while before placing it back, it could hold the connection for a longer period of time (but not that long. probably for a minute?).

i can't figure out what is the problem. I've changed the USB cable and still no change. could it be the battery has problems or is it a hardware problem?

many thanks to anyone who could help (tho i'm not optimistic since this part of the forum seems quite dead)
[JAMin, XDA Neo, S200 Software Upgrading] Dr.Thrax:
well

Now...this is vry important ...... plz do at ur own risk...

remove the battery

Cut ur data cable (USB) and u'll find a white wire in da bundle of wires ... connect it to the battery plug near the camera

All the others , u connect to the last plug...(there are 6 plugs for putting battery...do not connect to the middle ones)

now connect the USB cable to ur "xp" pc.

the pc will recognize the device and start syncing...

run the rom u want AFTER COMLETING SYNC ... It is sure to succeed ...

plz if any thing happend let me know
[JAMin, XDA Neo, S200 Software Upgrading] srespiral:

I losted a lot of times comm upgrading Roms and NOTHING HAPPENS! (sorry for screaming...) Try to search some info at forums but....

-Try to close your upgrading soft (PC)

-Switch off-on your phone

-Connect usb cable again and try to upgrade now.

(maybe it refuses 2 or 3 times the upgrading, but I was trying and after 4 times it was like ever!)

Please, make it as your own risk.

Good luck friend!!

I have same Problem PLease Help

Have S200 G3 in Tri Color screen that gets to 50% on ROM load before it starts shutting off n on. It does the same thing if it is plugged into a pc via usb cable w/ battery installed after a short period of time.

It does not turn off n on it it is simply sitting there w/ the battery installed. Only when it is plugged in w/ a USB.

Does some 1 have access to info on phone recovery via flash card and Rom that I can use.

If not steps on resolving the problem long enough to load a basic Rom on the unit.
[JAMin, XDA Neo, S200 Software Upgrading] dpast:
Provide better break down, if possible w pics of actual steps. Ex. I don'd understand what you mean about the white wire and middle conectors in battery section. Only allow the other 2 to connect or ???

Decided to do a Registry restore after having some issues with the phone. I used PHM Registry Editor and after the restore was done i was asked to do a reboot. After doing this the phone freezes on startup. I get the background, taskbar on the top, and the lines saying "Phone" and "Contacts" on the bottom, but thats it.

The keys also light up when i press them.

Any idea what to do? If all else fails i will do a hardreset, but thats the last option.

[HD2 General] wigwam12:
I am having real problems with my push gmail account.

I suspect I may have part of the answer but not all.

I am finding that sometimes emails are just not coming through as new emails.

In some cases when I send/receive or so an activesync it will even "see" that there are 1-3 email (ie it counts 0/3 etc) but will not bring them to the inbox.

I think that one way it gets confused is if, say, I have had a new email which it decided not to d/l and then I read it on the computer but I then get more emails from the same person replying about the same topic

Even if I get other new emails it just will not d/l any new ones until I have deleted the semi-unread/semi-new ones from the inbox - as you can imagine this would be a real issue if they are ones I need to keep!

Another possible culprit I wondered was if the account was signed into at the time by Gmail Mansger in FireFox.

I tried sending one having disconnected GMM and it sent through a new one [admittedly I had deleted the prior non-fetched test ones by this stage.

It is driving me batty.

Anyone able to shed any light please?
[HD2 General] wigwam12:
I have played a fair bit.

If there is an email in my gmail account newer than on my phone but that I have read online that seems to screw up the downloading. It seems to see how many there are are I don't know where it puts them.

If I delete all these and then try to send one sometimes it works fine, other times I have to manually sync to get one and I can't find a pattern at all
