The Google track record with new releases is dodgy enough that we suggested waiting a few weeks before buying the new Pixel phones. The Google Pixel 4 is an impressive phone with a number of advanced software functions, but it is poorly disappointed by the limited battery life. Although the Pixel 4 XL offers more endurance, it still doesn't last as long as we would like. The battery life is not the only problem that owners of both phones have encountered. We have run into a few other Pixel 4 issues and we've discovered some of the most commonly reported help forum issues. But we are not only here to complain, we are also going to explain how these problems can be circumvented or where possible resolved.
Whatever your problem, the first thing to try is a software update. Make sure you are connected to Wi-Fi and quickly check Settings> System> Advanced> System update, and then tap Check for update and install all available updates. [1
Let's tackle it immediately; the battery life of the Pixel 4 and Pixel 4 XL is disappointing. There is no real solution for this – Google should have installed larger batteries in both phones – but there are plenty of ways to live with it less. We don't recommend that you do all of these things, but turning off the things that you don't appreciate can give that battery a big boost.
- We do not want to compromise and we do not like grain functionality, so consider buying a good portable charger, a fast charger and a wireless charging station for the desk and bedside table before you continue reading. to keep your Pixel 4 up to date.
- The Pixel 4 should work well by restricting apps that you do not use often, thanks to Adaptive Battery – you can enable it via Settings> Battery> Adaptive Battery – but you can go one step further and view the complete list of apps and games on your phone and remove all apps that you don't need.
- It is a good idea to review app permissions from time to time for security reasons, but there may also be battery benefits. Go to Settings> Apps and notifications> Advanced> Permission management and revoke all permissions that you think the apps do not really need. Pay special attention to Location and reduce the number of apps that is always allowed .
- Although the new Google air gestures can be useful, they certainly affect the battery life because the Pixel 4 is vigilant for movement in the area. If you don't like them, go to Settings> System> Motion Sense and switch it off.
- Switch on Dark theme via Settings> Display . Since the Pixel 4 has an OLED screen, where pixels are illuminated individually, the battery will not drain as quickly as most do not burn; dark backgrounds require less power.
- The 90Hz refresh rate is one of our favorite things about the Pixel 4, but there is no doubt that it requires a heavy load on your battery. Go to Settings> Display> Advanced> Smooth display and you can disable it.
- Tweak more display settings. There are three things that will help that we have not covered yet and that are all accessible through Settings> Display . Reduce first Screen timeout as far as you can stand, and make sure in Lock screen display Always on is off and finally in Styles and backgrounds choose a background that is static and predominantly dark.
- Switch on Battery saving . You can do this via the notification screen or by going to Settings> Battery> Battery saving . It limits background updates, kills some visual effects, stops collecting locations and other background app activities, stops listening to "Ok, Google" and switches to Dark theme . You probably do not always want this, but tap Set a schedule and you will find the option to activate it automatically with a certain battery percentage, or based on your daily routine, what factors when you usually your Pixel 4 charges and decides when to turn it on to make sure you get it there without power.
- You can find a few more ideas in our general tips for the battery of the smartphone.  Annoyance: apps that are accessible with fingerprints do not work with face unlocking
An annoying disadvantage of the new face unlocking in the Pixel 4 and Pixel 4 XL is that many apps do not yet accept it as biometric authentication. It is possible that the banking app that you used to open a fingerprint scan on your Pixel 3 insists that you now type your full password on the Pixel 4. This applies to a large number of banking apps and other apps such as PayPal and Starbucks.  Unfortunately you can do nothing but wait. Developers must update their apps to support the new Google API. We contacted banking apps to ask when they would update and most responses were not very encouraging. It may be worth telling your bank that this is something you want in the hope of speeding it up, but realistically it can take months before support is added.
Care: Face unlock works with eyes closed
A few people worry that someone can hold your Pixel 4 to your sleeping face to unlock it. In its current position, unlocking works even when your eyes are closed. Google will release an update that adds an option for you to indicate that your eyes must be open for face unlocking to work. Until then there are a number of solutions that you can try.
- Use a PIN code, pattern, or password instead. You can set them in Settings> Security .
- With the lock mode, you can hold down the power button and then press to lock to quickly turn off biometric data if you are worried someone is going to try to force your phone against you to unlock. You can activate the Lockdown mode via Settings> Display> Advanced> Lock screen display where you must enable the Lockdown option. If you use it, your Pixel 4 will return to PIN, password or pattern unlock.
Problem: white balance and colored lights
Fortunately, this probably has no effect on most people. According to a Reddit message, picked up by a few sites, the Pixel 4 camera has a problem with colored lights where it seems to be trying to fix a shot with extreme colors and eventually changing to another, inaccurate color. There is also a discussion on the Google support forum asking for a manual white balance check. There is no solution for this, but Google can make adjustments that will be rolled out in future updates.
- The problem is not present in the RAW image files, so open the camera app and go to the settings, then tap Advanced and switch RAW + JPEG control . This saves the RAW file separately and allows you to export and edit it on your PC or use an app such as Snapseed on your Pixel 4.
Bug: clicking on sounds in video recorded in third-party apps
Some Pixel 4 owners have had a strange problem with video recorded in apps such as Instagram and Snapchat where background noise can be heard. There is a discussion on the Google support forum and on Reddit. Some people describe it as a popping sound or as a metronome, but it seems that it only happens when you use a third-party app to record video, not when you record video in the standard camera app. We have not been able to reproduce this problem and it is not clear how widespread it is.
- Simply use the main camera app to record video.
- Make sure you are informed via Settings> System> Advanced> System update, and then tap Check for update . Open the Play Store app, tap the three horizontal lines at the top left and then tap My apps & games and Update all .
Problem: Motion Sense does not work  If you experience problems making Motion Sense movements work, you are not the only one. It's a little handy, but some people have also reported other issues, as discussed on the XDA Developers forum. It is also important to note that Motion Sense does not work everywhere; it is currently only available in the US, Canada, Singapore, Australia, Taiwan and most of Europe.
- Start with to Settings> System> Motion Sense and ensure that it is switched on. You can tap the individual options here to see an animation that shows exactly which gesture to use. Assuming it is already switched on, switch it off and on again and try again.
- Restart your Pixel 4 or 4 XL by holding down the on / off button and then tapping . restart.
- screen protector on your Pixel 4 or Pixel 4 XL, remove it and test the gestures again.
Annoyance: smooth display is not always turned on
The revelation that the screen of the Pixel 4 and 4 XL is not constant using the 90Hz refresh rate to reduce the impact on the battery caused a stir. It has been found that the refresh rate of 90Hz may only be switched on if the screen brightness exceeds 75%. Google has said it will release an update to make the higher refresh rate work with different brightness levels of the screen, but it is not yet clear what that will look like.
- While waiting for an update that may open more options or change the behavior, you can always run the Pixel 4 display at 90Hz. Go to Settings> About Phone and tap Build Number seven times to unlock Developer Options . Now go to Settings> System > Developer Options and there is an option labeled Force 90 Hz refresh rate . Tap it and switch it on, but be warned, it will drain your battery faster.
