Fill in your details: Will be displayed Will not be displayed Will be displayed. If you can do without it, you can likely disable it. For example, on one of our test iPhones, the Moment app, which tracks location and activity throughout the day, used power in the background for nearly 94 hours over 7 days, claiming about 5 percent of overall battery use during that period. Close quit unused apps below. However, well-managed location services consume only a moderate amount of battery power.
For example, using the Maps app on an iPhone or Android phone for GPS directions for a short trip will consume minimal battery life, as these apps are designed to minimize GPS use; having the screen on during that navigation will consume significantly more.
This is, in part, why long navigation sessions use so much of your battery—you likely keep the screen on for the duration, and the screen draws a lot of power. You can take advantage of the previous tip going through the battery-usage screen to find big offenders: You can, however, set a systemwide location limit: In addition to push email, which automatically notifies you of new email messages as they arrive, smartphones support push notifications, which allow apps to provide new information, sound alarms, display reminders, and more, instantly.
If you get a lot of notifications, that energy use can add up. If a particular app or service say, Twitter or your email client is constantly producing notifications, consider disabling notifications for that app. As a bonus, fewer push notifications means fewer interruptions in your day and less time spent using your phone which, of course, also helps your battery last longer.
If you get a lot of notifications but have reasons or just a predilection to keep them coming, consider disabling notification vibrations instead. Every time your phone vibrates, it uses energy to move a little motor in the phone; over dozens or hundreds of notifications, that power drain adds up. AirPlay claims better sound quality and longer range, thanks to its use of a higher-quality audio format and your existing Wi-Fi network, but AirPlay uses quite a bit more of your battery than Bluetooth.
Some of them may be described above. Many people recommend disabling Bluetooth on your phone to get better battery life.
But Bluetooth was designed from the start to minimize battery usage, and it has only gotten better over time. In our testing, having Bluetooth on but not actively connected to a device used a negligible amount of battery power over several hours. Even when connected to a Bluetooth LE Low Energy device that regularly communicates with your phone, such as a recently made fitness tracker, Bluetooth uses very little of your battery.
The lesson here is simple: Use wired headphones, if you have them. A similarly common suggestion for extending battery life is to disable Wi-Fi. Although that may sometimes be true on a computer, smartphones are designed differently: While an app may still be loaded in RAM temporary memory , the app is unlikely to be doing stuff in the background to drain your battery.
Finally, quitting apps can actually have drawbacks: You likely want them to perform those tasks—force-quitting the apps will prevent them from doing the very things you gave them permission to do.
In that case, force-quitting it is a safe approach. You can then wait for an update to the app that, with any luck, fixes the bug. Restarting applications repeatedly will probably cost you more battery life than leaving them alone, and any automatic task manager will itself be demanding power constantly from your phone. As we mention above, many apps that use your location do so only intermittently—with the exception of a few bad apples, or apps that really do require constant location tracking, most apps are well behaved in this respect.
Instead, follow our tips above to check if any of the apps consuming the most battery life also track your location. Many people, and even smartphone vendors such as Apple, claim that using Wi-Fi for wireless data consumes less battery than using a cellular signal, so you should use Wi-Fi whenever you can. Where you will see differences is in areas where LTE coverage is poor. As we explain above, your phone uses significantly more power when trying to find and connect to a weak signal.
We found that after an hour of Web surfing, an Android phone had used roughly 4 percent of a full battery more when we were driving in a car than when we were stationary with a strong LTE signal; an iPhone used 8 percent more of a full charge. The difference will vary by phone, carrier, and locations, of course. Both iPhones and Android phones include a hands-free feature for accessing their respective virtual assistants.
Although this feature is convenient, it requires your phone to constantly listen for that special phrase, which uses some power. In our testing with an iPhone 6s Plus and a Nexus 6P, we saw a negligible difference in battery usage between having the always-on virtual assistant enabled or disabled over a two-hour period. If you find that your phone claims it has 80 percent of a charge left but dies a few hours later, try this procedure.
A common warning around the Internet is that you should use only the charger that came with your phone. Several warnings are woven into this claim. In reality, the phone itself contains all the circuitry responsible for charging its battery. This is why you can charge your phone using the USB port on a computer, a USB battery pack, or a charger in your car—the phone is designed to charge from a variety of power sources that can produce a wide range of current.
For example, the charger that ships with an iPhone supplies about 1 amp of current, but the phone can also charge from a 0. For example, if you use a recent iPhone with a charger that can provide up to 2. Finally, you may read warnings that a cheap third-party charger could damage your phone. Or how much volt will need to charge that batteries?
I like to build circuits.. Jeremy Fear No, that charger would not be able to charge those batteries. Only a proper charger that is configured for NiMH charging is recommended. Dick This was a great article. When I first used solar lights in the yard and the batteries eventually failed I could not find maH ones anywhere.
I succeeded in locating maH by mail order from China. I always worried that the difference in spec would be a problem but I could not find any information on the Web about it then. Are they old batteries? Maybe you should consider replacing them. Dmac Hi, I bought a digital camera and the sales guy told me to charge my Kodak Ni-MH batteries for 4 hours before use, I charges for 6 hrs.
I assumed I should charge for 4 hrs every time but the battery manual recommends Should I listen to the sales guy or charge as per the manual. Or does anyone know how long I should charge my batteries? BatteryStuff Tech Maybe the batteries were only partially charged when you bought them. Sometimes the batteries are fully charged when the leave the factory, but when they sit on the shelf for months they do drain some.
As long as the charger is an automatic charger, there really is no harm in charging the batteries for 4, 6, or Once they reach full capacity, hopefully the charger should stop charging.
What I put in there: Capacity may differ, but that only affects runtime for the device. Rechargeable NiMH batteries are a compatible replacement for the one-time use Alkaline batteries.
Julia Hi, I want to buy an adapter for my car since it is too old to have the place to be able to plug in and listen to my Ipod. I always heard that just a plane invertor is too high a voltage.
If I get a amh charger, will I be able to play my Ipod off of it without damage? Same for a cell phone? It is rated at 6v output, but is showing Is this usual to this type charger? It is specifically for NiMH charging on the label, so maybe the circuitry turns up the voltage at initial hookup? I just bought this to charge a 4 pack of ma AA size batteries. The charger is very warm to the touch with a red charging LED showing. No instructions came with it. BatteryStuff Tech I cannot confirm if that behavior is normal since we do not sell that particular model charger.
I recommend checking with the manufacture of the charger for technical help. My question … our video baby monitor came with three 1. We charge them using the supplied cable that just plugs into the handheld monitor.
The batteries that came with the monitor are slowly dying so I would like to replace them. However, some brands may have higher capacity than others. It will run your monitor for longer than say a mAh battery. Is it safe to use 4 alkaline 1. BatteryStuff Tech Please refer to technical help from Kodak for the answer to your question. Steven Very useful info — thanks. Is it common to have very different performance within a group bought in the same package? Also, I doubt I have charged them even 75 times, after mostly using them in digital cameras, Over a two year period.
Is there any justification to complain to the retailer? But this does not give your situation any less validity. Have you measured the voltages of the batteries?
Beatlearl I had to bookmark this site because I know smart when I see smart and after reading some of the articles on your site you guys are smart. Yes, before you use your new NiMH batteries for the first time you need to charge them fully.
After using it and wondering why the battery was already low, I looking in the manual and am now charging it fully. BatteryStuff Tech Not charging full capacity and discharging in the first initial uses can cause the memory effect.
Closely monitoring the capacity of the batteries would be the way to determine if there was any negative effect. Plz Help me with the exact time!!! BatteryStuff Tech At what rate does your charger charge at? Amin Which is the best battery mAh or mAh? Can i charge mAh battery in this charger? BatteryStuff Tech I am not familiar with the battery charger you mentioned, so I cannot answer that question. But the higher the mAh rating on a battery is, the more capacity it has. This translates to longer runtime for your application before needing to recharged again.
I would like to thanks you for giving wonderful understanding. BatteryStuff Tech Since we do not sell that specific charger, I cannot confirm if it will be safe to use on a mAh battery. BatteryStuff Tech This questions is like saying your cars holds 20 gallons. How long does it take to refill it? That depends entirely on how much is left and the rate the fuel flows through the nozzle at the gas station. As long as it takes? Usually a smart charger will have some light indicator informing you when the battery is fully charged.
Luis I used http: The result is 5. They are new, so I wanted to fully charge them. BatteryStuff Tech I recommend you measure the resting voltage of your battery pack. This will tell you the state of charge of the battery. Bob Measuring a battery at rest will not tell you the state of charge.
You can read 1. If you want to measure voltage do it under load, believe me I know over 30years in the electrical trade. EnewsDigest Thanks for the excellent article and detailed reply to all our doubts. My question is if I can measure the mAh remaining in a 1. The idea is that, then I can exactly recharge for a specific period of time without over charging the battery. Say for example, if I know that mAh is remaining I can charge for two hours with a charger with mA output. Or chargers are designed to use specific capacity?
BatteryStuff Tech If the voltage is nominal and the chemistry matches, you can tehcnically use the same charger. But keep in mind the charge rate is like current flow. If you have a larger capacity battery, it may take much longer to bring the charge up.
Or if the current is too much for a small battery, it can damage it. Ketan OK — my question: Ineed to calculate scenarios, such as drive a 1 watt load for certain number of minutes etc. A battery with the specifications you provided will have. With your battery you could run a 1 watt load for about 30 minutes, though a little less, like 20 mins, would be recommended. This is very helpful and interesting info. Thank you for taking the time to educate us about these things. I knew they were used for the 2-way radios but I wanted to check before using them in my headphones.
I wonder if they heat up…? JanD I purchased a Coldheat chargable glue gun and the 4. BatteryStuff Tech Some manufacturers send there battery packs only partially charged, and require you to charge the battery prior to use. Proper Care and Feeding: What does NiMH stand for? What is meant by battery memory?
What is the mAh rating mean? What is the best application for NiMH batteries? How many times can a NiMH battery be recharged? What applications are not good places to use NiMH batteries? Can I use a higher rated mAh battery in my electronic device i.
