Galili 1570mAh Battery for Nexus One Review

I got this Galili 1570mAh battery for my Nexus One and I have run several tests to see how it compares to my stock battery. I could not find any reviews on this battery so I figured $15 is cheap enough to give it a shot and see.
Test setup:
N1 OEM battery used for 5 months or so.
Galili 1570mAh battery used for 2 full charge and discharge cycles (according to my research it is a myth that you have to do discharge/recharge cycle few times to get full capacity in lithium ion batteries)
I tested using following steps:
1. Fully charge the battery, give it an extra 30 minutes or so at 100% charged.
2. Hold the power and trackball button to go into Bootloader mode. This is great for battery testing as the power drain over time is identical each time, as only screen is using power and there are no power saving feature kicking in like screen timeout etc.
3. Unplug the power supply and start timer.
I used video camera to keep track of time as I didn’t feel like staring at my phone for over 3 HR’s.
The original battery tested out to around 3 Hrs 15 minutes before the screen went dark. The Galili time fluctuated around 2 Hrs 52 to 2 Hrs 54 minutes. I run the tests 3 times or so over span of 2 weeks with almost identical results.
Conclusion: Yet another battery that lies about its capacity. It seems to be the norm that all the aftermarket battery manufacturers are inflating the capacity information. I found this cool web site where there are bunch of them tested.
batteryboss.org
This is OK battery for a backup but I was counting on getting higher capacity in the same footprint. It looks like none of the batteries out there can beat the original N1 battery.

thanks for the review!! Shame its crap!

So the lesson here is to fork over a little more for a genuine Nexus One battery and don't go cheap with the generic batteries.

That's my recommendation after buying batteries from eBay that wouldn't power up my phones.

I have only ever bought batteries for all my phones off ebay and never had an issue with any of them. They have all performed about the same as the official OEM counterparts. Now SD cards is an story... lol

Lithium Polymer
Why aren't lithium polymer batteries used more? I remember my ooooollllddd sony ericson phone had one....I think it was model t-something...LoL! Isn't it supposed to be better than lithium ion?

Uh, the Nexus One does have a Lithium Ion Polymer battery..

Largest battery that stick fits under the stock back cover

Are there any larger batteries that will still fit in the stock back. I want an "extended battery", but am not willing to sacrifice my Active X case to get one.

For all intents and purposes, no. There is a 1600 mAh that sells for some ridiculous price like 60 dollars or something, but anyone who spends that much for a 100 mAh bumb at BEST is moronic. Also, Stock batteries typically have an extremely high real life mAh, usually 95-98% of rated mAh. Any aftermarket will not have as high of a percentage, so a 1600 will probably be just barely better than stock.

This is not true the 1600 battery is a seidio and seidio batteries are pretty well known for being higher quality than stock. Tag on some extra charge on top of that and it will probably be quite noticable. A couple years ago when I had a touch pro 2 I bought a seidio battery that had 250 mAH more than stock and in real life usage I almost got double the time out of it. I changed from charging every night to every other night.

That is absolutely based on no truth. Seido is ABSOLUTELY not better than stock. In fact, NOTHING beats stock batteries.
batteryboss.org
No Seido battery has better than an 84% real life mAH to rated mAH. Stock batteries have at MINIMUM 95% real life mAH to rated mAH.
84% of 1600 = 1344 mAH
95% of 1500 = 1425 mAH

I think I am just going to hook a car battery up to it..........it will be months before I have to recharge

Just get Shorai Battery, much lighter and easier to carry around.

muyoso, do you have the research from the site to back up those numbers? I'm not about to go digging for it myself...
There are a variety of factors that reduce a lithium ion battery's performance. First of all, lithium batteries have a higher internal resistance than their nickel metal-hydride and nickel cadmium counterparts (counterparts in the sense of their use in cell phones over the years). This is one reason why they heat up quite a bit during both charge and discharge, and consequently "age" faster when existing in a warm environment.
Lithium batteries self-discharge at around 8% per month, and during this time typically suffer a permanent capacity loss when left unused. Batteries that were produced and stored in a warm place for too long will certainly not charge to as high of a capacity as another identical battery that was produced and began earlier discharge cycles in a real-world environment.
Lithium batteries do not have a "memory," which is the effect that nickel cadmium batteries are reputable for carrying over the course of many charge/discharge cycles. In other words, your battery isn't going to suffer because you never let it run dead before charging it all the way back up. It doesn't matter. However, leaving it on a charger with Wi-Fi, Bluetooth, and a high-definition porno on simultaneously will only negatively effect the battery due to the heat generated from current delivery.
Some batteries are simply better than others. This holds true even among batteries of the same brand, capacity and application. The way they are handled, stored and used determines the life and performance of the battery in your phone. In this case, do not drain your battery to 0% before charging it back up. It's typical for lithium batteries' capacity to permanently drop by 15-25% within one year's use.
If you have a spare cell, charge it to about 40%, take it out and put in the refrigerator. Also, make sure you check the manufacturing date on the packaging, as I said before, storing for long periods without a 40% charge or regular charge/discharge cycles will result in a lessened capacity.
Just figured I would throw a few facts out there. I began using lithium batteries for robotics projects a number of years ago when they became much more prevalent.

The guy behind batteryboss.org did extensive testing. Stock batteries were all rated at near rated capacity. Seido batteries were not. He clearly explains his testing procedures. I have read over that site pretty thoroughly and trust his numbers and technique.

[Q] Strange Battery voltage reading

I am getting strange battery voltage readings while the battery is fully charged . Ideally the peak voltage should not cross 4.2 volts for Li-ion batteries ,IMHO . Also I saw the Moto G review on Anandtech where the battery voltage is given as 3.8 V . But my battery reads a voltage of more than 4.3 volts . So I'm a bit worried about the long term reliability of this battery or my battery in particular . Has any one else checked this on their Moto G . You can see this info by using the secret dial code *#*#4636#*#* ( Lots of other interesting stuff under this menu )
I have a dual SIM variant of this phone .

I don't think it's an issue, mine peaks at 4.325 as it approaches full charge (it's above 4.2 from about 80% up when charging), it will then 'relax' to 4.194 once at 100% (even if still plugged). Other devices I own do similar. 3.8v is the nominal ideal voltage when the battery is least stressed (about 55% capacity) and perfect for long time battery storage.
If you wanted to be utterly anal about preserving your battery for eternity the strategy is never let it discharge below about 30% and never let it charge above around 70%. Lions will last for years and years and tens of thousands of charge cycles in those circumstances with no loss in capacity.

I own another droid device and the removable battery is rated 4.2 V 1500 mah. During charging it peaks to slightly under 4.2 V and reaches about 3.8 V at about 50 % .So it is safely under the 4.2 voltage limit. . Also many articles on battery university talk about 4.2 V being the peak . Hence the query
Is this the same observed by other Moto G owners ?

Mines also 4.3V at or near fully charged.

Maybe Its the moto g's secret of extra long battery life.....dangerously overcharging enabled by default (Also called bump charging)
Bump charging is known to destroy battery life
And since battery is internal...more profits for moto when people come to get them replaced WIN WIN!!

Hey I guess some users have had this phone for a week . Can some onecheck and post the peak battery voltage ? Mine has reduced from 4.33 to about 4.25 .Also looks like the battery life has reduced a bit
Also how does one reset the battery calibration . Is it by keeping the power button pressed and letting reboot twice?

Sorry for 3 months old bump, but I've got a response from Motorola and saw this thread.
X: Hi, my name is X. How may I help you?
(unknown): Hello, my name is [Me]. I want to ask you a question about Moto G.
X: Hello, [Me]. I will be more than happy to assist you on this.
(unknown): I used CPU-Z to look at a few details about Moto G's hardware and noticed that the battery voltage is 4.3V when fully charged. Is this normal?
(unknown): I've read on the internet that Li-Ion batteries shouldn't exceed 4.2v
X: Let me check on my resources. Please hold on.
(unknown): Thank you.
X: No problem. Do you already have our Moto G or you're planning to buy one?
(unknown): I already have one, just checked the voltage with an app (the default android hardware info menu has the same values so it's correct) and I was wondering if it's a bad thing.
(unknown): Is Moto G's battery of higher quality?
X: Okay and yes, it is.
//
I said something about higher quality because I read this: learn.adafruit.com/li-ion-and-lipoly-batteries/voltages
"Nowadays you may also be able to purchase 4.35V cells! These are the latest chemistry, they have a little more power as indicated by the voltage being higher than 4.2V. They tend to be cylinder lithium ion's used for laptop batteries, and lights so its not terribly likely you'll just run into one unless you're looking for it."
So does this mean we shouldn't worry about it?

Samsung Galaxy Express 2 and bigger battery

Hi!
Has anyone tried bigger batteries for Express 2 (SM-G3815)? I am considering to buy Mugen 2300mAh battery since it should fit in with original backcover. So it doesn't make your phone any thicker. Mugen battery gives almost 10% more capacity so I think it should also make battery life 10% better. Anyone tried Mugen 2300mAh battery or other for Express 2?

I not tryed this battery or a higher one, but 10% more i donth think is so big diel.
BTW android 5.1 with cyannogenmod 12.1 drain the battery faster than android 4.4 original stock.

Battery capacity

So i have the battery monitor widget app, and it shows that calibrated capacity is around 2600 mAh, so this means the battery has degraded, right?
I have been searching for original batteries, but on AliExp**** there seem to be only batteries from around 2014, and some people say the battery swells after use etc., so i'm hesitant to buy from there. Any other sites maybe?

the test is not so accurate.
i would stick to this battery untill you feel the battery life is horrable.
you can but a new battery for about 17$.
