I'm thinking about getting a spare battery. Would my calibration be off if I swap batteries often? I'm planning a trip and gonna get a spare just in case.
Yeah, it would be pointless if you are constantly swapping them because although the batteries are the same or similar they will have different capacities....I use two batteries myself so I always have one ready....I like it better that way....

I don't quite follow. First you are saying it's pointless to get another battery if you swap them often. And then you say you have two batteries yourself.
Each battery has it's own capacity/memory. This is not governed by the phone. However, the phone may not reflect the actual battery level if you swap batteries at different power levels. That's not so much of a big deal, as the main intention is to keep the phone powered. I've swapped batteries often with one of my other phones and haven't noticed any problems. The battery that was older didn't last quite as long as the new one, but it still worked.

Ah, OK. Misunderstood.
What does "calibration" actually do? Will it improve the efficiency of battery usage?
Allegedly, I can't tell you for sure how much it will extend battery life because I don't do it....but supposedly if you do it faithfully for a week or so it works

Basically your battery has a memory.. some what, so its gets use to its regular drain and recharges. There's a couple of ways to calibrate it but I like to run it down till its dies and then charge it by usb for a slow recharge.. I do this atleast once a month.

It will just give you an accurate reading of your battery. You will still have the same amount life calibrated or not.
An example would be, let's say your battery is at 15% and it dies in just 10 minutes. Or if it's at 5% and the phone takes forever to die. That means the battery isn't calibrated.
Hi did anyone experiance this kind of battery consumption? 3days 14hours and 45min and still have like 7%?
Not personally, I use my phone too much to get that kind of life out of it. Based on what I know about the drain when it's screen off and sleeping, though, I think it's well within the realm of possibility with light use.
I get like 24 hours out of mine... with some light-moderate use... used to be better when I bought it but then after installing some apps it just starts degrading a bit I guess
Well, rechargable batteries do degrade over time, and the more apps you have on a device, generally the less time it will last on battery, partially because those that run in the background consume more system resources and partially because those that update data in the background will keep your phone "awake" more of the time.
If I wasn't using my phone and just let it idle (sync on, airplane mode off) I'd get like 12 days of battery life. That's what I like about the NxS, unlike other smartphones it does actually last longer when not used.
hi
i am getting around 10 to 12 hours. wifi always on. mostly watching youtube videos. netbrwosing. gaming.
2g phone calling
still i think i am getting reasonably good back up
Disabling wifi,gps,bluetooth and reducing screen brightness will improve battery life.

That's no issue, but working as intended.
Other phones are using the same technique, but they are hiding it by showing the 100% the phone never reached, that's why they drop to 95-97%ish right after unplugging and from there drain normally.
I experienced battery drowning after using app's like maps or latitude. I had to kill them manually, now I'm cleaning the phones memory regularly. That safes a lot of battery life for me on the one hand, but on the other hand loading app's isn't as fast as before.
It's the classical trade-off between battery life an usability. And 10-12 hours are normal for me if I'm using my phone a lot.

Well, depends on the manuf. if they want to "hide" it or not, they could also set 95% capacity as "100%" displayed. All batteries got a safety feature of some kind

same here.
never rooted or installed a custom rom.
in 2g idle it lasts ~14days
9 to 13 hours ,was looking at getting maybe better battery but dont think theres one
So 95% is the new 100% because my phone won't charge to 100%. It just stops at 95%.

If I'm not mistaken, the "charge to something about 96%" is a safety measure to increase the lifetime of the battery? Why would one want to push those last few % and lower the lifetime?

All Android phones have this "charging safety feature".
Unless you plan on using the same battery and phone for the next ten years, you are highly unlikely to notice any degradation in the battery health. I have been using one of my OEM Samsung Nexus batteries for 2 years now (it is the same battery that came with my Samsung Moment and used on an Instinct HD as well). This particular battery has been topped off on all three phones and external chargers probably 100's of times. It still charges to a full 4.19v and stays full even sitting on my nightstand for a week or two.
The "Safety mechanism" in the charging code that has been brought up over and over again is included in all Android phones. It is nothing new. The problem is that in other devices, the battery meter reads 100% when it reaches the safe full level at the batteries temperature (usually between 4.188 and 4.190). The Nexus S has an error in the driver code that causes the meter to read inaccurately(95-98%) even when the voltage reaches 4.19. I don't believe Google did this intentionally, as it would cause many misinformed people to constantly bump charge their batteries in hopes of reaching 100%. It would have made more sense to have the meter read 100% at the safe full level.
In any event, the fix for the issue is here, and already being applied to some Nexus S kernels, including the one in the OP. It's not just "cosmetic".

Bought my nexus s day one and it charges to 93%. I've noticed turning wifi on after plugging it in to charge does boost it to 98. But I always leave wifi off overnight. Don't want pesky google plus emails waking me up lol.
Overall, after nearly a year of use I'm happy with the battery life of my phone. You get used to how far you can push the phone in daily use and which settings to use.

I know people are always complaining about battery performance, or see stories of how someones phone will go from 100-40 in an hour and half to two hours. I think I've found a solution (notice how I said I THINK). I've seen random battery fluctuations on my device for months now, some days it lasts longer than others (obviously data off, wifi off, and all that good stuff) but the battery life would still be eaten away like crazy. Here's what I noticed a few days ago: I went to sleep and when I woke up the next day my battery life had dropped 20 percent overnight, and everything that sucks battery was off. It confused me because that doesn't happen unless I leave data or wifi on. So I looked through the phone and I turned off "Standalone GPS services" one night and went to bed again. The next morning, the phone battery had only dropped 2 percent!
tl;dr turn off Standalone GPS under Location and security settings. IT may help your phones battery life significantly
Hope this helps with your battery performance folks, and if this has been brought to your attention already, then sorry for the repost!
just thought i would reply
first of when i sleep if i need the alarm i turn the flight mode on as the battery only uses between 1-4 % a night normally 2
i dont have a standalone option only turn gp on and off
r800i 2.3.4
but i dont have any battery issues really if my battery is draining fast its because im playing a game or browsing the web alot
a good tip is
use wifi instead of data when a wifi network is available but keep wifi off when not in use.
too many people either leave wifi on all the time which wastes alot of battery or never use wifi as there confused and always use data connections even when at home (major battery killer)
What happens with my battery is that if I leave the phone on standby overnight it'll gain about 10% and that's not even in airplane mode.
But as usual my battery does drain quite a lot when playing games using wifi and all that. Using EDGE drains more than using wifi.
I always charge my phone every night so would turning off the gps help much during the day?

Each has its own pro's and cons. Here is a list:
Lithium ion:
-The lightest of all metals
-The greatest electrochemical potential
-The largest energy density for weight.
-The load characteristics are reasonably good in terms of discharge.
-The high cell voltage of 3.6 volts allows battery pack designs with only one cell versus three.
-It is is a low maintenance battery.
-No memory and no scheduled cycling is required to prolong the battery's life.
-Lithium-ion cells cause little harm when disposed.
-It is fragile and requires a protection circuit to maintain safe operation.
-Cell temperature is monitored to prevent temperature extremes.
-Capacity deterioration is noticeable after one year (whether the battery is in use or not).
Lithium Polymer:
-Lithium polymer chemistry differentiates itself from Lithium Ion in the type of electrolyte used (a plastic-like film that does not conduct electricity but allows ion exchange - electrically charged atoms or groups of atoms).
-The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.
-The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry.
-Cell thickness measures as little as one millimeter (0.039 inches).
-Can be formed and shaped in any way imagined.
-Commercial lithium polymer batteries are hybrid cells that contain gelled electrolyte to enhane conductivity.
-Gelled electrolyte added to the lithium ion polymer replaces the porous separator. -The gelled electrolyte is simply added to enhance ion conductivity.
Capacity is slightly less than that of the standard lithium ion battery.
-Lithium ion polymer finds its market niche in wafer-thin geometries, such as PDA batteries.
-Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
Ice Cream Sandwich (Beta) already has this feature off by default.. but great tip anyway.
yeah i know my battery sucks too but it vary's sometimes
You could try out apps like juice defender. It disables your data connection and enables it every 30 minutes for example, to update whatsapp etc. When I am at home, I use our WiFi network. My play has the best battery life of all my friends phones and I'm a heavy user, playing a lot of games and using the internet too.

You need to try the ultimate version. You can select what happens on specific apps. So apps that dont use the internet, the data will be disabled whilst playing them
Also, you can set it to automatically turn data on/off depending on your location so you connect to wifi at home ect
I find it very useful

You should let your phone die at least once a month, then charge it all the way to 100%
With the phone turned off. I promise you will get the best life out of your battery. Good Luck MF.

No.... Just, no.
Same problem
I had the same problem, I think I have to buy a new battery
A couple of things...
When applying an update on Android platforms, the battery stats are usually wiped, this results in wonky battery drain and charging indications and it usually lasts a few days to as long as a week.
So, the short story is, see if it doesnt correct itself after a week.
On occasion, Android updates dont quite go right and regardless of how Google 'intends' for updates to go, 25% of the time, youll end up doing a factory reset after a firmware update (poor performance, new error messages, wonky power issues including higher than normal battery drain and slow charge rates).
Again, the short story is, after a week, if it hasnt corrected itself, Id suggest a factory reset, then give it another week to see if the battery issue corrects itself. Obviously, realize that if during that week you install anything new that this could affect your battery life. I personally try to keep my phone as stock as possible and disable as many stock apps that I know Ill never use (my Note 3 is at around 25 stock apps disabled and Ive only installed 15 of my own apps, none of which would likely have a negative impact on battery).
Best practices for the proper care and feeding of Lithium Ion batteries is pretty straight forward. There are alot of myths out there from Nickle Cadmium batteries that just dont hold true for our current generation of batteries.
1. Whenever possible, keep the battery charged. If you have an outlet available, plug your phone in, regardless of whether its fully charged or not.
2. Try to keep your battery / device in typical room temp environments (ie a temp range of 60-85 degrees F). Obviously, this isnt always possible but dont intentionally leave a battery / device sitting on the dash in your car in direct sunlight (direct sunlight can raise the temp by as much as 25 degrees higher than the actual ambient temp), dont put your battery / device on top of a heater, etc.
3. Drain the battery periodically (referred to as a full discharge*), currently, the rule of thumb is once every 3 months and re-charge with the phone OFF, once the phone has a 100% charge (use the volume rocker to see the current charge without having to boot the phone), unplug the charger, THEN boot the phone. This gives Android a chance to see what a full discharge and charge should be (and cycles the battery giving the electronics inside the battery a chance to see the same discharge / charge).
* Note that a full discharge in todays components is when a device shuts itself down when on battery power due to lack of power in the battery to continue operating said component without damaging the battery or the component any further. Do NOT continue to turn the device on after it shuts down in this manner without first plugging external power into the device as this will likely dramatically shorten the life of the battery.
The last rule is most important..
4. IMPORTANT! Use your device like you normally would. The above three are tips for making a battery last as long as possible but when and if your phone makes you change how you live your life to any degree of extremes, you've forgotten the point of what your phone is.
