Yeah pretty much that. That's why we need a lab rat to do some testing about that

I read a post where someone said their N1 felt hot, like laptop hot. That draws some concerns. Anyone read anything similar? Or know anyone with similar first hand experience?

if hot than normal
but if hot like laptop then it will b weird especially with small device

One of the comments at the bottom by a 'Rick'.



So unless hes a fanboy or he has a defect unit, I don't see why he would be making it up.

most probably a defect unit, imagine how many google staff tested on this phone before official release

Google staff would have picked up the 3G connectivity issue, but that didn't happen...

I've seen another post somewhere reporting of a hot device problem. Someone left it charge overnight while running an application/music in the background. It went hot and not responsive in the morning.

That is exactly what we played with the Teknologist kernel (well, one of the features of course)..If you are on Hero, our governors are set to "performance" for min and max..Even for wake up

As for the GMaps navigation, Malaysia is NOT yet supported for point-by-point navigation..I also heard about the hack in XDA..I will try to see if I could get my hands on it and will give that a shot..but of course at least one week after I got my Nexus One..I'm sure other than rooting and flashing custom ROM, I don't want to jeopardize my Nexus One blindly compared to my Hero..hahaha..

I will test the GPS around Port Dickson area..We have 3G here which is not hogged by extreme users..I will show the length of time it takes to connect to the GPS satellite while on the move, and the accuracy of it

If it was connected with the charger and left, then I am sure it would've heated up..Even my Hero gets very hot when its charged and being used at the same time on long hours (particularly 2 - 3 hours of continuous usage)..I doubt its the processor that heats up..I think it must be the battery rather..I personally will test that on my phone too and see if it happens..On a side note, when this phone was being manufactured, it was winter seasons..SO I guess they were happy with warming themselves up in the cold weather..hahahaha.. XD

Regardless, I will run a check too..First charge will be 8 hours with phone switched off..Second charge I can guarantee the next afternoon..lol..with phone turned off..then the third charge after that with phone turned on..I'll update you guys..

Heating up happens to my Hero too..but not responsive..now i'm shaking..lol..

Ah..here is the post.

Thanks for the alert bro..Thats really scary!
My personal opinion, he was silly to let the phone run and charge (first time) overnight..I don't really charge with applications running, but I do charge with the phone on.. :S I will do more reading on this issue and see if its a malfunction of that phone only or really a bug..I gotta be careful with my Nexus One..I dont want to wait for one month just to get it fixed..

Its getting scary now..LOL!! 2 days more to go..I'm getting impatient already..I just wished Fedex would come knocking on my door anytime saying please sign here..

Should I use N95 or iPhone camera to record the vids? Suggestions guys?

Pls take the best 1. No mood seeing an iphoney vid. LOL
About the heat , do effect any bad things to N1 based on that user comment? I think its just only, when u holding phone for hours in ur palm, it did to heat up becoz the heat comes from ur plam. And I don't see any of this bad thing inside any gadgets websites review.. do sumkind of iphone fan throwing bad thoughts about N1??? Maybe lol.

Charging overnight shouldn't be a problem. Its fine for lithium-ion batteries from what I've gathered.

Sure, he left music playing all night too, but still. If its true, it kinda makes it sound like the N1 isn't very durable.

I myself have gadgets that heat up when being charged and occasionally have left it on over night while left it on and used. But they never have malfunctioned on me.

A bit of a worrying note when I've been really interested in getting a unit myself.

Meanwhile, anyone knows how long it takes to fully charge the N1? (not first charge)

@ ~tera~

Read the cases on the heat. One said it gets laptop hot, no device will get that hot just from the heat of your palm.

The 2nd case posted was cause someone left it charging overnight with he music app on.

i wonder based on what source did you make your assumption.

Yeah..well, I will trust my own experience rather than the person's experience..For now, we just "read" it here and there..In future, we can test everything on my Nexus One..Two days guys..Thats all we need before we can start testing it out Then we will not have to believe in other people's doubts..

yea..that's true... can't really trust on every reviews as there are lots of fanboys around.

Sounds like you are going to put your N1 through a test dummy run for us

Thanks anyway!

From that thread on overheating, and the number of people posting. It DOES get hot when charging. But in most gadget's cases, thats pretty normal. Just hopefully it won't be too hot.

Could you do a test and have the N1 running multiple processes and apps without the battery? If thats possible. Then at least we can know if the heat is largely from the battery or the processor itself?

Nothing is perfect ... My V3xx, E52, ... were heat up during heavy net browsing, especially when I used it at place with low receptions. Low reception = h/p have to transmit (TX) at much higher output, Imagine, 100mA (normal) to 1A at full TX strength. In this case, your h/p can drains your 1500 mAh (E52) in about an hour!!..

BTW, software's bugs also can make system using full resources. Ever experiencing laggy when opening certain sites or apps or some period of time? Same goes to mobile phone's apps too.

So, the tip is, use only what you need .



BTW,almsot all Li-ion batteries have safety electronic circuits built-in to prevent overcharge and optimize the charging....Even Nokia 3210 battery has the builtin circuit with termal sensor!. If the safety circuit faulty, your battery can be overcharged and can be hazard/dangerous too, because it can explode!!.

thank you.

i dont think its possible to run it without the battery..its a "charger" and not an "adapter" but nevertheless, i will try it though

Yeah..My Nexus One is the guinea pig here I guess..haha..I don't mind though..I'm curious myself too.. Someone else can test the future phones maybe..unless we get some donations for a test phone..

@vermins
Owh I c, sry for not reading all of those heat up comment. But its do possible to heat up when str8 using ur smartphone for hours ,ur hand will sweat up and it will produce some heat to ur phone.

About Google map navigation issue in previous page.
Currently I'm using digi rm5/day EDGE internet , the google maps works fine BUT google map navigation usage in Malaysia sumtimes sucks.
Coz its using old map for Malaysia satellite view and no street view for any places here( I just tested it at penang and kota bharu, other famous places like kl I dunno whether its avail or not.)
So u can only experience half of google map navigation feature here. So I hope google should rescan/update satellite view on Google map here and put sum street view for us as android user here.
Its really sucks when I the 1st time I use it just to see how street view works here..
The good thing is Google map navigation did lock current position faster than papago x5 and it works inside the building too. The gps precision when u are moving around with vehicle are just same with papago and also recalculating other route while navigate are also same.

Yeah, this is exactly what I'm afraid off. I'm not exactly a google fanboy. And after reviewing some of the videos, N1 best compliment user who use google services extensively, like gmail (I'm using hotmail, yea, the java scripted page is horrible and buggy, but been using it for 10 yrs now, won't want to ditch it), gtalk (not a fan as none of my friend is using it), google earth (map not up to date, and google map cannot display traffic direction unless we zoom to detail map). These are the thing that use extensively.... I would need to switch everything to google (especially mail) and persuade my friends to use gtalk, if I want to maximize N1... haha.

About phone become warm, its normal under heavy usage and indoor when reception signal is low. However, battery that stay warm (or hot) for long period of time during charging is not good for the battery. It will reduce the battery capacity, and has chance of explosion. Normally battery get slightly warm when it approach full charge capacity. The fail-safe circuit detect peak voltage, and will start pulse charging intermittently (to maintain power usage). However if usage (I mean heavy usage) and charging occur at the same time, it may interfere the peak detection. Hence continuously charging the phone (battery).

Could be an overlook feature in N1? I don't know.

Exactly..Not to forget, the background applications when we have multi-tasking available (ehem) some dynamically written procs can terminate power hogging background applications but in most cases, they don't have this (especially on mobile phones)..

As far as Li-ion batteries are concerned, most of the gadgets I have used so far don't have the best circuit breakers yet though..If you have a laptop, you will definitely know that after sometime, the battery starts to lose its retention time..This is because of poor circuit breaking techniques applied to the digital gadgets..I have to say, Apple has a very good batter handling systems in their notebooks..Their batteries charge in "packets" and sometimes it will display 100%, sometimes it will display 99% and sometimes even 98%..The circuit breakers break the charging before the max capacity is reached and this saves the battery from damaging.

I like the way bahathir said the last line:



That was really cute..LOL! He scared you with explosion then suddenly said thank you..haha
