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..

got a new battery and..

and I don't remember where, but I read somewhere, some time ago, that when you get a new battery, you should fully charge, and fully discharge the battery a few times.. Is this a good idea? does it help the battery?
are there any tips, like doing a complete cycle every so often?
Also, well, I got this on Amazon so I'm hoping it really is brand new. The brand new batteries are supposed to be dead, not charged, right?

Lithium ion batteries are never shipped "dead", bad things can happen (read up on it). So when you buy a lithium ion battery it always has a charge on it. They also don't have a "memory" like older batteries do so just use it normally. When i got my Naztech battery it was fully charged!

Ouch.. So does that mean my battery isn't going to be as good as an OEM battery? It looks like it's a legit samsung battery, it has the same model #
Anyway I charged it up fully, then I had to send in my phone to Samsung, so I took it out. When it gets back I'll see how my battery life is.

Li-ion batteries aren't supposed to have a memory, however I read a lot of good articles that argue no batteries have memory. However that being said, I've had the best luck out of cycling batteries like that. We have 7 Samsung batteries for our Fascinates, and always just run them down and swap to the next battery. Whenever I get a new one I charge it up, then run it down a few times.
I always charge them, they do come partially charged, but usually not 100%.

Any battery "woes" of memory is all placebo affect much of the time. Unless the phone doesn't get a balanced charge it will have no memory. But I think these batteries are one cell so you don't have to worry about it.

If you have 7 batteries isn't it a pain swapping them back in to charge them?

you can get chargers, like just a wall charger that you can drop a battery or two in and it'll charge without the phone.

Do I need a kernel or something to use the Mugen 3200mAh battery?

I was reading around the forum and through all the things about extended batteries and stuff to decide that I was going to buy the Mugen 3200mAh one.
My question is Droidzone has this thing called "EBatt/EBFix=Droidzone's fix for Extended Batteries". Do I need that for my extended battery or will it have no problems with charging? I believe his fix is set for 2400mAh but mine is 3200mAh.
I put in my extended battery and it was at 0% charge, only thing I notices was Battery Widget Widget Pro didn't know how many mAh so I assume neither does the phone (because its not an official HTC battery).
I'm doing what the Mugen User Guide is telling me, which is to charge the phone for 8-12 hours even if it shows full charge for the first 4-5 times.
Correct me if I'm wrong but I'm assuming that the battery will charge but take a longer time to charge but will still show 100% (also will the battery % be completely wrong all the time because the phone doesn't understand the maximum capacity is greater now).
So back to my initial question, do I need to flash a extended battery fix kernel or just calibrating the batteries should work?

As far as extended batterys go, yes you need a kernal which supports it. I'm shopping around for a Yoobao battery and I'm finding out which kernal I need which will support the information for the battery.

Any luck on finding one? So the battery won't charge to full capacity without the appropriate kernel?
With the kernels I've only found droidzone and I don't particular have the time to test all the different kernels on my phone.
I tried doing the full charge without using a different kernel, I will see the results of this soon hopefully.

It should charge to full but you won't see the real capacity.

Mine charges to 54% then jumps 100$. It doesn't seem to be giving me the full amount I expected. It charged more once for an hour or two after I let it get to 99% then switched off and charged again. Then booted and let it hit 99% and repeated the process about 3 times. Then I wiped battery stats. Now I'm letting it relearn the whole battery thing. It's dropping fast right now... But I think a few full charge cycles are required.

No. You do.not need a special kernel. Mugen battery's are made to.be used with nonroot phones.

[Q] Battery Issues

Hi everyone,
I've had my Sensation for about 14 months now and for the past month I've been having battery issues. Primarily, it's very quick to lose charge and will lose charge even while charging from the wall. First I bought a replacement battery but was still having the same issues. I've started using Better Battery Stats and Battery Monitor Widget but I don't have anything out of the ordinary running. In fact, not a lot is running at all. BMW has allowed me to see how the charging is going though which has been nice. During this period I have used Elegancia, Bruce's CM10, and am currently on ParanoidAndroid. All experienced the same issues.
Last night, for example, I put the phone on the charger at 16 percent. It charged up to 22 and then started the downward slide to death and I ended up waking up 35 minutes late.
Where do I go from here so I don't have to constantly be paranoid about my battery levels?

Sounds like you might need another battery. In better battery starts did you notice any unusual wake locks? This could drain a battery. But since it looses charge even when charging I'd think it was the battery. I personally was experiencing some battery issues myself finally I broke down and got a mugen 3800mah battery from mugen. It was expensive but really worth it for Me.with really heavy and constant use I get 20 hours out of my battery, with normal use I get two days. I'm also running paranoid Android rom. For me the big battery solved my issues. Only one draw back, it does make your phone thicker. New back included with battery. This didn't bother me much because of the excellent battery life I receive. Now I finally don't. Worry about battery. However it's expensive at about 95 dollars. But I was so fed up with poor battery life it was worth it for me. You have to be careful when buying inexpensive batteries because there are a lot of fakes going around. And the mah is not really what it says it is on the packages. You can test the battery and make sure it is what it's advertised to be. If you don't want to go with that large of a battery you can also try anker extended battery. It's a lot less expensive and is a good battery. I personally needed more juice so I went with the big battery. I know you said you replaced the battery but sometimes the bargain batteries go bad quickly. It makes me suspicious of the battery because it's even dropping while charging. This is strange. If you ruled out any apps or wake locks that might be draining the battery I would buy a good reliable battery. The draining while charging is a red flag. I'd say the battery is going bad. I don't at all regret my purchase of the big battery. It for me, solved my issues. I do Hope this helps and I wish you the best. Hopefully you will get your issue resolved soon.

its either an issue with the battery or the battery reporting.
Only thing you can really try is to charge it up to 100%, wipe battery stats in recovery, then let it empty totally and charge it up again, see how its behaving. There is a chance that its the reporting that is off.
otherwise this looks like the battery is on its way out im afraid

Argh. I hope it's not the replacement battery too. I got a replacement HTC battery. The problem I'm having getting anything useful from Better Battery Stats is that rarely am I off the charger. In the settings it says I can log while charging but it may mess up the stats so I've shied away from doing that. I'm not against getting a bigger, better battery but I would hate to do that and have it actually be something else hardware-wise where I would need to get rid of my phone.

I'll give this a try if I can get it back up to 100%. Is the reporting in Recovery always correct? The battery never has issues charging while it's in Recovery mode. If that's the case then I'll charge it to 100% in recovery and then wipe and start fresh.
Thanks

I don't think it's the battery. This phones have errors in battery readings. I feel your pain man. Mine is from T-Mobile (Sensation 4G) and it discharges if I use it even at lowest brightness when it's charging too.
If I reboot, I get the battery boost. I have tried EVERYTHING I read here and nothing worked. I even have 4 batteries. All of them in good condition.
I even tried three times discharging it fully and without turning it on, charge it in the night and when I wake up 7-8 hours later, it's still charging. I tried wiping stats, changing ROMs, changing the usb cable and the charger. Everything... I believe it's a hardware issue. (Thank HTC for that) I'm not buying another HTC when I have to upgrade.

Interesting...so if you were to charge the phone in recoery how long do you think it would take to get to 100%?
I would definitely do what you said, charge in recovery then wipe battery stats and go from there.
If you're interested in having something to compare to, it takes my phone about 3 hours to charge to 100% (by the way I'm using an Anker extended capacity battery), with a peak current usually around 800 - 900 mA. Fully charged I have somewhere around 4100 mV. If you haven't already, I'd suggest adding a Battery Monitor widget with mA, mV, and % available being displayed and it will be pretty easy to get an idea what's going on.

I'm leaning towards hardware issue too. That's why I figured I'd post and see if there was anything else that I can try. It's also why I don't really want to buy an expensive battery since who knows what it'll fit next. I know what you mean about the reboot battery boost. You can almost gamble and bet on percentages when you reboot. I've seen 50% swings before.

In recovery I would guess that it wont take very long to charge to full. I have battery monitor widget installed and while plugged into the wall with my 1.0A charger, it will typically pull 100-200mA but sometimes it'll spike to 700-900mA. No rhyme or reason. When idling and functioning properly, without a charger plugged in it drops 9-100mA. Sometimes though while charging it'll sit at negative 100-200mA.

HA! Just rebooted my phone and it went from 68% to 100%. So I rebooted into recovery, it also said full so I wiped stats.

I normally get 2 to 3 mA drain with the phone sleeping. When charging you may not necessarily get close to the 1 A current delivery of the charger straight away, typically it will ramp up over time and reach peak charge current as it gets closer to 100%. Once at 100% it wants to just "trickle" charge to maintain 100% charge until the charger is disconnected, so any wakelocks etc. that cause a current drain during that "trickle" charging will actually decrease battery charge until the charger ramps up to compensate for the drain. Random spikes in charging current would suggest a hardware problem where the electronics are struggling to properly govern the charging process, as would a large negative current drain with the charger plugged in. Silly question but what's the actual plug connection to your phone like? Nice and solid, pins all OK?

Bought a new battery, anything specific I should do when replacing?

I just bought one of those Anker 2200 mAh batteries since mine has been starting to go. I'm wondering if there is anything I should do before I put it in so the phone can calibrate to a new battery. Something like wiping battery stats, letting it charge to full then discharge completely, or anything else. What do you suggest?
I am on a recent PAC-man CM based rom.
Thanks!

You'll get all sorts of advise when it comes to a new battery. Some people have some really elaborate routines but I really don't think that is necessary. I think you already have a good idea what to do.

Others say that there is no need to wipe data and cache or wipe battery stats. As long as you charge the new battery on the first time it was charge for about 8 - 10 hours even it its 100% already.

I got 2 of those with an anker charger on amazon. I switch between them and my OE Sammy battery (mostly on vacations) with no issues. I just pop them in and go. Sometimes they aren't even 100% since if I know they are going to sit around out of the phone for long its best if they aren't 100% charged.
